UNSPSC 51191946: Thiamine mononitrate

This classification denotes a b vitamin with the molecular formula C12H17N4OS.NO3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 8K0I04919X, chemically known as 3-(4-amino-2-methylpyrimidyl-5-methyl)-4-methyl-5,beta-hydroxyethylthiazolium nitrate but more generally known as thiamine mononitrate, which bears US NIH Compound Identifier 10762. European Medicines Agency schedules Thiamine mononitrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15528MIG.

Most nations, for tariff and trade purposes, schedule thiamine mononitrate under HS 29362200 and SITC 54113. As of Q4 2014, THIAMINE MONONITRATE remains US FDA's Preferred Term for this commodity. Thiamine mononitrate bears US NLM identifiers UMLS ID C0039844 and NCI Concept Code C87669. SMILES: CC1C(SC[N+]1CC2CNC(NC2N)C)CCO.[N+](=O)([O-])[O-].

UNSPSC 51191946 Thiamine mononitrate is a Commodity code covering vitamin and nutritional supplement procurement by state and local health, corrections, and social-services agencies. The recent opportunities in the system, however, show minimal direct activity under this specific code; the two posted solicitations address sodium bisulfite (a water-treatment chemical) and generic multi-source pharmaceuticals and OTC products more broadly, neither of which map cleanly to thiamine mononitrate procurement. State and local governments do procure vitamins and nutritional supplements for institutional food service, medical facilities, and correctional food programs, but the current opportunity pipeline does not reflect active demand for this specific commodity at the state or local level.

The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued the most substantial recent opportunity—an RFP for generic multi-source pharmaceuticals and OTC products with a response deadline of March 26, 2026—which may encompass thiamine mononitrate as part of institutional vitamin inventories, though the solicitation does not isolate this commodity. The City of Meriden (Connecticut) posted an IFB for sodium bisulfite due July 29, 2026, which is unrelated to the code's scope. Absent explicit evidence of active state or local thiamine mononitrate solicitations, this code shows limited recent procurement activity; firms should monitor MMCAP and state health-department facility contracts for institutional vitamin opportunities that may be tagged to related pharmaceutical codes.
