Stable Isotopes for Biologics

The National Institute of Standards and Technology (NIST) seeks quotations for stable isotopes for biologics research, with quotations due September 17, 2026. There is no set-aside; this is an unrestricted commercial item procurement under FAR.

Place of performance is Gaithersburg, Maryland, with delivery FOB destination to NIST's Intramural Biomedical Research Building (IBRR) at 9600 Gudelsky Drive, Rockville, Maryland 20850, within 30 calendar days after award during normal business hours (8:30 a.m. to 5:00 p.m. Eastern Time, Monday through Friday, excluding Federal holidays).

Base line items include: 25 liters of deuterium oxide (D₂O) with minimum 2H enrichment of 99.9%; 50 grams of 13C glucose with minimum enrichment of 99.9%; 500 grams of 15N ammonium sulfate with minimum enrichment of 99.0%; 100 grams of 13C methanol with minimum enrichment of 99.0%; and 50 grams of 13C deuterated glucose with minimum 13C enrichment of 99.0% and 2H enrichment of 97.0%. Optional line items mirror the base items at reduced quantities: 1 liter of D₂O, 5 grams of 13C glucose, 25 grams of 15N ammonium sulfate, 10 grams of 13C methanol, and 5 grams of 13C deuterated glucose.

Quoters must provide firm-fixed pricing for all base and optional line items, technical acceptability documentation demonstrating compliance with minimum isotopic enrichment requirements, completed solicitation provisions, active SAM registration, and representations regarding business size status and country of origin. The NAICS code is 325199, All Other Basic Organic Chemical Manufacturing; PSC is 6810, Chemicals. Award will be made to the responsible quoter submitting the lowest-priced, technically acceptable quotation.
