Re: Registration Statement on Form S-1, as amended

Ladies and Gentlemen:

This opinion is furnished to you in connection with a registration statement on Form S-1, as amended (the “Registration Statement”), filed by Chromocell Therapeutics Corporation, a Delaware corporation (the “Company”), with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), for the proposed offering (the “Offering”): (A) by the Company of up to (i) 2,002,159 shares of common stock, par value $0.0001 per share, of the Company (the “Common Stock”), which number includes up to 261,151 shares of Common Stock subject to the underwriters’ over-allotment option described in the Registration Statement (collectively, the “IPO Shares”); (ii) 100,108 shares of Common Stock (the “Representative’s Warrant Shares”) issuable upon exercise of warrants to be issued to the representative of the several underwriters named in the Registration Statement (the “Representative’s Warrants”), which number includes up to 13,058 shares of Common Stock subject to the underwriters’ over-allotment option described in the Registration Statement; and (B) by certain existing stockholders identified in the Registration Statement (the “Selling Stockholders”) of up to 2,686,554 shares of Common Stock (the “Selling Stockholder Shares”). The IPO Shares, Representative’s Warrant Shares, and Selling Stockholder Shares are collectively referred to herein as the “Securities.”

We are acting as special counsel for the Company in connection with the Registration Statement. In connection with this opinion, we have examined and relied upon the originals or copies certified or otherwise identified to our satisfaction of the Registration Statement, including the exhibits filed therewith, and have also examined and relied upon the agreements entered into in connection with the Offering, including the Underwriting Agreement in the form filed as Exhibit 1.1 to the Registration Statement (the “Underwriting Agreement”), the minutes of meetings and resolutions of the board of directors of the Company (the “Board”) as provided to us by the Company, the organizational documents of the Company, including the Amended and Restated Certificate of Incorporation of the Company to be filed with the Secretary of State of the State of Delaware prior to the sale of any Securities (the “New Charter”), and the Amended and Restated Bylaws of the Company to be adopted by the Board prior to the sale of any Securities (the “New Bylaws”), and such other documents as we have deemed necessary for purposes of rendering the opinion hereinafter set forth.

In addition to the foregoing, we have relied as to matters of fact upon the representations made by the Company and its representatives. In our examination of the foregoing documents, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, the authenticity of the originals of such latter documents and the legal competence of all signatories to such documents. Other than our examination of the documents indicated above, we have made no other examination in connection with this opinion.
