00HCTBDE-2007-41570-41574 The Centers for Disease Control and Prevention (CDC) intends to award, on a sole source basis, a purchase order to Cambridge Isotope laboratories, Inc, 50 Frontage Road, Andover, MA 01810-5413. A purchase order will be issued for custom synthesis of the following organic compounds in various quantities: (+/-) BENZO[A]PYRENE-R-7,T-8,C-9,C-10-TETRA-HYDROTETROL (Ring-13C, 99%). Justification for other than full and open competition is considered due to continued need to match existing products for on-going human subject exposure research being conducted by the CDC, National Center for Environmental Health. Failure to procure existing Carbon-13 labeled standards in purities and batch lots currently offered by Cambridge Isotope Laboratories will alter or contaminate assays required for on-going research being conducted by the CDC. This is not a request for competitive proposals and no solicitation is available. Firms that believe they can provide the organic chemicals by predetermined and specified purity are encouraged to identify themselves and give written notification to the Contracting Officer within 5 days of the publication date of this synopsis. Determination by the Government not to compete this proposed action based on responses to this notice is solely within the discretion of the U.S. Government. Information received will be considered solely for the purpose of determining to conduct a competitive procurement. Inquires may be sent to Russell T.
