Description

NON-COMPETITIVE COMBINED SYNOPSIS / SOLICITATION

Title: L-Glutamic Acid

(i) This is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice. This announcement constitutes the only solicitation; proposals are being requested, and a separate written solicitation will not be issued.

(ii) The solicitation number is 75N98026Q01122 / PCA-NIMH-04010. This solicitation is issued as a Notice of Intent (NOI) for a non-competitive combined synopsis/solicitation to award a contract or purchase order without providing for full and open competition (including brand-name, if applicable).

This acquisition is conducted under the authority of FAR 12.603, Streamlined Solicitation for Commercial Products or Commercial Services, and is not expected to exceed the simplified acquisition threshold. Additional authority includes 41 U.S.C. 1901 and FAR 6.302-3(a)(2)(ii).

The National Institutes of Health (NIH), Office of the Director, Office of Acquisitions, intends to negotiate and award a firm-fixed price on a non-competitive basis to Sigma-Aldrich Inc., 3050 Spruce St., Saint Louis, Missouri 63103 for the requested L-Glutamic Acid (2,4 ¹³C2-99%). 

(iii) The solicitation document and incorporated provisions and clauses are those in effect through Federal Acquisition Circular (FAC) 2026-01 dated March 13, 2026.

(iv) The associated NAICS code is 325180 – Other Basic Inorganic Chemical Manufacturing, and the small business size standard is 1,000 in number of employees. This requirement is not a set-aside for small business.

(v) Description of Requirement: This requirement is to obtain a special Sigma-Aldrich Inc., 13C2 L-Glutamic Acid 2,4 99%,1x1 gram.   The Magnetic Resonance (MR) Spectroscopy  Unit  and  Core  have  been  conducting  several  in  vivo  carbon-13 (1*3C)  spectroscopy  projects  with  infusion  of  13C  labeled  chemicals.  Because natural abundance of 1*3C is only 1% and is too weak to be detected.  Therefore, we need to use chemicals with enriched 13C to increase 13C signal intensity. With these 13C labelled chemicals, we will be able to detect brain metabolism and to accurately measure the concentrations of several important metabolites. The 13C MR spectroscopy methods developed in our group is and will be applied to many other research groups in NIMH and NIH for various neural science studies. Without this chemical, the institute will lose a powerful method in neural science research.

 (vi) Delivery Location: NIH, NIMH, 10 Cener Drive, Bldg. 10, Bethesda, MD 20892
