The National Institute of Standards and Technology (NIST) is seeking information from suppliers and manufacturers of organic chemicals for its Mass Spectrometry Data Center (MSDC) to support the development of the NIST/National Institutes of Health (NIH)/Environmental Protection Agency (EPA) Mass Spectral Library. The requirement includes a diverse range of organic compounds, with suppliers expected to deliver at least 75% of the chemicals listed in the provided draft chemical list, in quantities not less than 1 mg, with larger quantities permissible under specific conditions. These chemicals are critical for various applications in scientific research and regulatory compliance, emphasizing the importance of accurate chemical data in advancing innovation and safety. Interested parties should submit their capabilities and relevant information to Sadaf Afkhami at Sadaf.Afkhami@nist.gov by the specified response date, as NIST anticipates issuing a Request for Quotation in the first quarter of FY25, with contract awards expected in the second quarter of FY25.
