| Nature of Operations [Text Block] |
Enzon Pharmaceuticals, Inc. (together with its subsidiaries, “Enzon” or the “Company,” “we” or “us”), manages its sources of royalty revenues from existing licensing arrangements with other companies primarily related to sales of certain drug products that utilize Enzon’s proprietary technology. In 2017, the primary source of the Company’s royalty revenues was the revenue received from Nektar Therapeutics, Inc. (“Nektar”) pursuant to the execution of a Second Amendment (“Nektar Second Amendment”) to the Company’s Cross-License and Option Agreement (the “Nektar License Agreement”) with Nektar, which generated non-recurring royalty revenues of $7 million (see below). The receipt of this $7 million satisfied all future obligations of royalty payments pursuant to the Nektar License Agreement. Prior to 2017, the primary source of the Company’s royalty revenues was derived from sales of PegIntron, which is marketed by Merck & Co., Inc. (“Merck”). Prior to 2013, the Company was dedicated to the research and development of innovative therapeutics for patients with high unmet medical needs. The Company currently has no clinical operations and limited corporate operations. The Company has no intention of resuming any clinical development activities or acquiring new sources of royalty revenues. Royalty revenues from sales of PegIntron accounted for approximately 100% and 5% of the Company’s total royalty revenues for the three months ended June 30, 2018 and 2017, respectively, and 80% and 11% of the Company’s total royalty revenues for the six-month periods ended June 30, 2018 and 2017, respectively. In March 2018, Merck notified the Company that a downward adjustment of approximately $313,000 in royalties was necessary, resulting, primarily, from product returns. Accordingly, at December 31, 2017, the Company accrued a liability to Merck of approximately $313,000 and partially offset that amount by the $88,000 that was due to the Company from Merck. Thus, the Company recorded a net payable to Merck of approximately $225,000 at December 31, 2017. In January 2018, Merck paid the $88,000 to the Company, which increased the liability to $313,000. During the second quarter, Enzon earned approximately $60,000 of royalties, which reduced the royalty payable to Merck to $253,000 (See Note 11 Royalty Revenues and Accounts Payable.)In April 2013, the Company announced that it intended to distribute excess cash, expected to arise from ongoing royalty revenues, in the form of periodic dividends to stockholders. On February 4, 2016, the Company’s Board adopted a Plan of Liquidation and Dissolution (the “Plan of Liquidation and Dissolution”), the implementation of which has been postponed. (See Note 10 Plan of Liquidation and Dissolution.) The Company may be entitled to certain potential future milestone payments contingent upon the achievement of certain regulatory approval-related milestones with respect to Oncaspar. The milestone payment obligations were assumed by Shire plc (“Shire”), when it acquired the Oncaspar product portfolio previously owned by Sigma-Tau Finanziaria S.p.A. in July 2015. In February 2018, Shire indicated that it was in the The Company will not recognize revenue from Servier or anyregistration stage and awaiting further regulatory action. If Food and Drug Administration (“FDA”) approval is obtained for SC Oncaspar,, the Company would be entitled to a milestone payment of $7.0 million from Servier S.A.S. (Servier), which entered into an agreement to purchase the oncology business from Shire in 2018. There can be no assurance that the FDA will approve the Biologics License Application (“BLA”). Accordingly, there can be no assurance that the Company will receive any of the milestone payments related to SC Oncaspar or any other such milestone payments resulting from its agreements with any of the Company’s other third party licensees. of the Company’s other third party licensees until all current revenue recognition requirements are met.Under the Company’s existing agreements with certain third party licensees, the Company may be entitled to (i) potential future milestone payments contingent upon the achievement of certain milestones with respect to several other drug products in various stages of clinical and preclinical development and (ii) potential future royalty payments related to any future sales of these drug products. Due to the challenges associated with developing and obtaining approval for drug products, there is substantial uncertainty whether any of these milestones will be achieved. The Company also has no control over the time, resources and effort that these third party licensees may devote to their programs and limited access to information regarding or resulting from such programs. Accordingly, there can be no assurance that the Company will receive any of the milestone or royalty payments under these agreements. On June 26, 2017, the Company entered into the Nektar Second Amendment, wherein Nektar agreed to buy-out all remaining payment obligations to the Company under the Nektar License Agreement. In consideration for fully paid-up licenses under the Nektar License Agreement and for the dismissal with prejudice of all claims and counterclaims asserted in the litigation with Nektar, Nektar agreed to pay the Company the sum of $7.0 million, which satisfies all future obligations of royalty payments pursuant to the Nektar License Agreement, the first $3.5 million of which was paid within one business day of the effective date of the Nektar Second Amendment and the remaining $3.5 million was to be paid on January 6, 2018. Accordingly, the Company recorded revenue of $7.0 million and a receivable of $3.5 million in the second quarter of 2017. The $3.5 million receivable was paid in full in December 2017. |

| Basis of Accounting [Text Block] |
Interim Financial Statements The accompanying unaudited condensed consolidated financial statements have been prepared from the books and records of the Company in accordance with United States generally accepted accounting principles (U.S. GAAP) for interim financial information and Rule 10-01 of Regulation S-X promulgated by the U.S. Securities and Exchange Commission. Accordingly, these financial statements do not include all of the information and footnotes required for complete annual financial statements. Interim results are not necessarily indicative of the results that may be expected for the full year. Interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include legal and contractual contingencies and income taxes. Although management bases its estimates on historical experience, relevant current information and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ from these estimates. Revenues In accordance with Financial Accounting Standards Board (“ FASB”) Accounting Standards Update (“ASU”) No. 2014-09 (Topic 606), royalty revenues from the Company’s agreements with third parties are recognized when the Company can reasonably determine the amounts earned. In most cases, this will be upon notification from the third-party licensee, which is typically during the quarter following the quarter in which the sales occurred. The Company does not participate in the selling or marketing of products for which it receives royalties. No provision for uncollectible accounts is established upon recognition of revenues. (See Note 3.)Contingent payments due under the asset purchase agreement for the sale of the Company’s former specialty pharmaceutical business are recognized as income when the milestone has been achieved and collection is assured.

| Earnings Per Share [Text Block] |
Basic earnings per common share is computed by dividing the net income by the weighted average number of shares of common stock outstanding during the period. Restricted stock awards and restricted stock units (collectively, nonvested shares) are not considered to be outstanding shares until the service or performance vesting period has been completed. The diluted earnings per share calculation would normally involve adjusting both the denominator and numerator as described here if the effect is dilutive. The denominator would include both the weighted average number of shares of common stock outstanding and common stock equivalents. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method and shares issuable under the employee stock purchase plan. For purposes of calculating diluted earnings per common share, the denominator includes both the weighted-average number of shares of common stock outstanding and the number of common stock equivalents if the inclusion of such common stock equivalents is dilutive. Dilutive common stock equivalents potentially include stock options and nonvested shares using the treasury stock method and shares issuable under the employee stock purchase plan (ESPP). Earnings per common share information is as follows (in thousands, except per share amounts) for the three months and six months ended June 30, 2018 and 2017:
As of June 30, 2018 and 2017, options for 41,787 and 41,787 shares, respectively, were outstanding that have been excluded from the calculation of diluted weighted average shares outstanding, as they would be anti-dilutive since the respective options’ strike price was greater than the current market price of the shares. |

| Income Tax Disclosure [Abstract] | ||||
| Income Tax Disclosure [Text Block] |
During the six months ended June 30, 2018, the Company recorded approximately $1,000 of income tax expense for New Jersey state income tax. During the six months ended June 30, 2017, the Company incurred tax expense of approximately $2.7 million of which approximately $2.3 million was incurred during the second quarter of 2017. The recorded tax expense included $1.4 million as a discrete item for the three-month period ended June 30, 2017 for the tax effect of projected income reduction in future years. The Company continues to provide a valuation allowance against all of its deferred tax assets, as the Company believes it is more likely than not that its deferred tax assets will not be realized. Management of the Company will continue to assess the need for this valuation allowance and will make adjustments when appropriate. Tax benefits of uncertain tax positions are recognized only if it is more likely than not that the Company will be able to sustain a position taken on an income tax return. The Company has no liability for uncertain tax positions. Interest and penalties, if any, related to unrecognized tax benefits, would be recognized as income tax expense. On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was signed into law. Among its numerous changes to the Internal Revenue Code, the Act reduced the U.S. federal corporate tax rate from 35% to 21% for years beginning after December 31, 2017. In addition, the Act repealed the corporate alternative minimum tax (“AMT”) for years beginning after December 31, 2017 and allows companies with existing alternative minimum tax credit (“MTC”) carryforwards as of December 31, 2017 to receive refunds of the credits in tax years after 2017 and before 2022 in an amount equal to 50% (100% in 2021) of the excess MTC over the amount of the credit allowable for the year against regular tax liability. The Act also provides for an indefinite carryforward period for net operating losses generated after 2017 and limits annual utilization to 80% of taxable income. Net operating losses generated prior to 2018 continue to be carried forward for 20 years and have no 80% limitation on utilization. Our accounting is complete as of December 31, 2017 as related to the remeasurement of deferred taxes to the new tax rate of 21%, repeal of the AMT, receipt of MTC refunds and limitation of net operating losses generated after 2017 to 80% of taxable income. No provisional amounts were recorded as a result.As a result of the Act’s provision allowing for the refund of MTC beginning with tax year 2018, the Company has recorded MTC as a long-term receivable of approximately $1.9 million. |

| Liquidation Basis of Accounting [Text Block] |
On February 4, 2016, the Company’s Board of Directors adopted a Plan of Liquidation and Dissolution (the “Plan of Liquidation and Dissolution”), pursuant to which the Company would, subject to obtaining requisite stockholder approval, be liquidated and dissolved in accordance with Sections 280 and 281(a) of the General Corporation Law of the State of Delaware. In approving the Plan of Liquidation and Dissolution, the Company’s Board of Directors had considered, among other factors, the ability of the Company to obtain no-action relief from the SEC to suspend certain of the Company’s reporting obligations under the Securities Exchange Act of 1934, as amended, and the anticipated cost savings if such relief is granted by the SEC. After further consideration, the Company’s Board of Directors determined that it would be fair, advisable and in the best interests of the Company and its stockholders to postpone seeking stockholder approval of the Plan of Liquidation and Dissolution until a later time to be determined by the Company’s Board of Directors. If dissolution and liquidation of the Company pursuant to the Plan of Liquidation and Dissolution are approved by the Company’s stockholders and implemented by management, it is expected that the Company’s corporate existence will continue for the purpose of winding up its business and affairs, at least, through the year 2021, consistent with the expiration of the Company’s existing license arrangements that generate its royalty revenues. The Company has forecasted little or no royalty revenues for the years 2018 through 2021. This forecast is based upon a variety of estimates and numerous assumptions made by the Company’s management with respect to, among other matters, forecasted sales of the drug products for which the Company has the right to receive royalties, potential returns and rebates and other matters, many of which are difficult to predict, are subject to significant uncertainties, and are beyond the Company’s control. As a result, there can be no assurance that the estimates and assumptions upon which this forecast is based will prove accurate, that the projected results will be realized or that actual results will not be substantially higher or lower than forecasted. |

| Royalty Revenues and Accounts Payable [Text Block] |
During the fourth quarter of 2017, Merck corrected an error in their previous adjustment of royalties, noting that they owed the Company an additional net amount of approximately $88,000 and the Company recorded a receivable of that amount. In March 2018, Merck notified the Company that a downward adjustment of approximately $313,000 in royalties was necessary, primarily due to returns from sales in China in the fourth quarter of 2017. Accordingly, in December 2017, the Company accrued a liability to Merck of approximately $313,000 and partially offset that amount by the $88,000 that was due to the Company from Merck. Thus, the Company recorded a net payable to Merck of approximately $225,000 at December 31, 2017. In January 2018, Merck paid the net $88,000 that was due to the Company from the royalties adjustment it had made. Because this amount was included in March 2018 when Merck calculated and notified the Company of the $313,000 returns adjustment, the $88,000 received in January was recorded as an additional liability due back to Merck. Therefore, at March 31, 2018 the aggregate amount due to Merck was approximately $313,000. During the three month period ended June 30, 2018, Merck calculated and notified the Company that Enzon earned $61,000 of royalties, which reduced the aggregate amount due to Merck to approximately $253,000. |

Accordingly, these financial statements do not include all of the information and footnotes required for complete annual financial statements. Interim results are not necessarily indicative of the results that may be expected for the full year. Interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. |
|
| Consolidation, Policy [Policy Text Block] | Principles of Consolidation The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated as part of the consolidation. |
|
| Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. These estimates include legal and contractual contingencies and income taxes. Although management bases its estimates on historical experience, relevant current information and various other assumptions that are believed to be reasonable under the circumstances, actual results could differ from these estimates. |
|
| Revenue Recognition, Policy [Policy Text Block] | Revenues In accordance with Financial Accounting Standards Board (“ FASB”) Accounting Standards Update (“ASU”) No. 2014-09 (Topic 606), royalty revenues from the Company’s agreements with third parties are recognized when the Company can reasonably determine the amounts earned. In most cases, this will be upon notification from the third-party licensee, which is typically during the quarter following the quarter in which the sales occurred. The Company does not participate in the selling or marketing of products for which it receives royalties. No provision for uncollectible accounts is established upon recognition of revenues. (See Note 3.)Contingent payments due under the asset purchase agreement for the sale of the Company’s former specialty pharmaceutical business are recognized as income when the milestone has been achieved and collection is assured. Such payments are non-refundable and no further effort is required on the part of the Company or the other party to complete the earning process. |
