UNSPSC 51191944: Thiamine monochloride

This classification denotes a b vitamin with the molecular formula C12H17N4OS.Cl, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier X66NSO3N35, chemically known as thiazolium, 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-5-(2-hydroxyethyl)-4-methyl- chloride (1:1), but more generally known as thiamine monochloride, which bears US NIH Compound Identifier 6042. European Medicines Agency schedules thiamine monochloride or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10969MIG.

Most nations, for tariff purposes, schedule thiamine monochloride under HS 29362200. SMILES: CC1C(SC[N+]1CC2CNC(NC2N)C)CCO.[CL-].

UNSPSC 51191944 Thiamine monochloride is a Commodity code that in practice covers a much broader scope than its specific name suggests—state and local governments are actually soliciting under this code for chemical supplies, parenteral pharmaceutical products, and equipment used in municipal infrastructure, correctional healthcare, and water treatment operations. The recent opportunities show no thiamine-specific procurement; instead, issuers are tagging unrelated chemical and pharmaceutical commodities under this code, suggesting the taxonomy designation does not align closely with actual state and local buying patterns in this product family. The issuing bodies span municipal utilities (City of Meriden), county infrastructure agencies (Broward County), and state corrections and healthcare systems (Washington State Department of Corrections), indicating broad usage across different government verticals purchasing chemicals and medical supplies.

Activity appears concentrated in Florida and Washington, with municipal chemical procurement also visible in Connecticut. The Washington State Department of Corrections issued an RFQ for parenteral products, services, and equipment—including parenteral nutrition solutions, intravenous solutions, and controlled substances for incarcerated individuals across eight correctional facilities statewide, responses due October 7, 2026, with DOC encouraging small business, minority-owned business, women-owned business, and veteran-owned business participation and anticipating multiple contractor awards (up to three per region). Broward County, Florida posted a Request for Information on September 18, 2026 regarding DeZurik/APCO valves, parts, and repair services for wastewater treatment facilities, seeking to determine whether alternatives to the current sole-source provider exist before potential sole-source designation, with responses due September 29, 2026. The City of Meriden, Connecticut solicited bids for sodium bisulfite chemical supply for its Water Pollution Control Facility under IFB B027-15, due July 29, 2026. The code itself shows misalignment with actual procurement activity and may warrant review for reclassification.
