RE:		Enzon Pharmaceuticals, Inc.
		Form 10-K for the Fiscal Year Ended December 31, 2006
		Filed March 2, 2007
		File No. 0-12957

Dear Mr. Rosenberg:

By telephone on July 12, 2007, Dana Hartz of the Staff of the Commission provided certain verbal comments regarding the letter dated June 21, 2007 from Enzon Pharmaceuticals, Inc. (the “Company”) to the Commission, responding to the Commission’s comments on the Form 10-K for the Fiscal Year Ended December 31, 2006 (the “Form 10-K”) of the Company filed on March 2, 2007. Following please find our responses to the two verbal comments provided by the Commission.

Please revise the Form 10-K to name your independent valuation firm and provide consent. If you continue to believe that an amendment is not necessary, please provide a detailed explanation and provide us your proposed non-expert consent language.

Response:

We will disclose the name of the independent valuation specialist referred to in our Form 10-K. However, we believe that disclosure on a Form 8-K would be preferable to communicate this information. The Form 8-K would disclose the name of the independent valuation specialist referred to in our Form 10-K and the services they performed and would include, as an exhibit to the Form 8-K, the consent of the independent valuation specialist to being named in that Form 8-K and by incorporation by reference in each of our ’33 Act registration statements. As described in our previous response letter dated June 21, 2007, we have the agreement of Duff & Phelps, the independent valuation specialist, to provide their “non-expert consent” to be filed as an Exhibit 99.1 and to be named in our ’34 Act reports and ’33 Act registration statements.

We believe our proposal provides better disclosure to our stockholders and the market for the following reasons:

	•		The only disclosure in the Form 8-K would be that concerning our valuation specialist and the disclosure would specifically reference back to the relevant disclosure in our Form 10-K. We believe this will make the disclosure more understandable and would draw more attention to the newly disclosed information, rather than an amendment to the Form 10-K, which would add the name in the middle of the MD&A section in a less noticeable format.

	•		The information in a Form 8-K would be automatically incorporated into our current ’33 Act registration statements on Form S-3 and Form S-8, just as an amended Form 10-K would be, so there would be no timing difference in the disclosure whether filed on a Form 8-K or an amended Form 10-K. As a reminder, each of our ’33 Act registration statements were filed with the Commission and declared effective prior to the filing of our Form 10-K for the fiscal year ended December 31, 2006. Therefore, we would not have been required to file the consent of Duff & Phelps with those registration statements at the time those registration statements were filed.

A draft of the Form 8-K that we propose to file in response to your comment is attached hereto as Exhibit A.

By filing the Form 8-K, we believe that we would be addressing the issue raised by the Staff comment in a manner that provides clear disclosure to our stockholders and the market of the name and role of the valuation specialist.

Refer to your response to Comment #3. Since Rule 12-09 of Regulation S-X specifically asks for a schedule by major class of valuation allowance, we believe your allowance for doubtful accounts should be separately stated in this schedule to provide clarity to the investor.

Response:

We advise that the Company will separately state its allowance for doubtful accounts in such schedule in its future filings with the Commission.

The Company acknowledges that:

	•		The Company is responsible for the adequacy and accuracy of the disclosure in the filing;

	•		Staff comments or changes to disclosure in response to Staff comments do not foreclose the Commission from taking any action with respect to the filing; and

	•		The Company may not assert Staff comments as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

If I can be of any further assistance, please do not hesitate to contact me at (908) 541-8759.

Very truly yours,

/s/ Craig A. Tooman

In giving such consent, we do not hereby admit that we come within the category of person whose consent is required under Section 7 or Section 11 of the Securities Act of 1933, as amended, or the rules and regulations adopted by the SEC thereunder, nor do we admit that we are experts with respect to any part of such Forms 8-K and 10-K within the meaning of the term “experts” as used in the Securities Act of 1933, as amended or the rules and regulations of the SEC thereunder.
