UNSPSC 51191940: Thiamine disulfide phosphate

This classification denotes a b vitamin C24H36N8O10P2S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier HIX040UVAZ, chemically known as formamide, n,n'-(dithiobis[1-methyl-2-(2-(phosphonooxy)ethyl]-2,1-ethenediyl))bis(n-((4-amino-2-methyl-5-pyrimidinyl)methyl)-, but more generally known as thiamine disulfide phosphate, which bears US NIH Compound Identifier 3034217. European Medicines Agency schedules Thiamine disulfide phosphate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB22636.

Most nations, for tariff and trade purposes, schedule thiamine disulfide phosphate under HS 29362200 and SITC 54113. As of Q4 2014, THIAMINE DISULFIDE PHOSPHATE remains US FDA's Preferred Term for this commodity. SMILES: CC1NC(C(CN1)CN(/C(=C(\SS/C(=C(\N(C=O)CC2C(NC(NC2)C)N)/C)/CCOP(=O)(O)O)/CCOP(=O)(O)O)/C)C=O)N.

UNSPSC 51191940 Thiamine disulfide phosphate is a Commodity code that in recent state and local procurement activity covers a wide range of chemical, pharmaceutical, and equipment supplies rather than the narrow pharmaceutical compound its name suggests. The issuing bodies soliciting under this code span state departments, county government, and municipalities, each procuring distinct material inputs for specialized operational needs. Broward County, Florida recently issued a Request for Information on DeZurik/APCO valves, parts, and repair services for wastewater treatment compliance; the Washington State Department of Corrections solicited parenteral products, services, and equipment including parenteral nutrition solutions and intravenous products for eight correctional facilities; and the City of Meriden, Connecticut sought sodium bisulfite chemical supply for water pollution control operations. The mismatch between the code's nominal pharmaceutical scope and the actual procurement activity—which centers on industrial chemicals, valve systems, and medical delivery services—signals that the code is being applied broadly to capture miscellaneous chemical and equipment purchases across state and local health, corrections, and water treatment operations.

Recent activity concentrates in Florida, Washington, and Connecticut. Broward County's RFI (due September 29, 2026) sought valve suppliers capable of providing SCADA-compatible equipment and maintenance for wastewater compliance; the Washington State Department of Corrections' RFQQ (due October 7, 2026) required parenteral-product suppliers to deliver TPN and intravenous solutions within strict timelines (24 hours for PN bags, 8 hours for other products) across three geographic regions with aspirational small business, minority-owned business, women-owned business, and veteran-owned business goals; and the City of Meriden's IFB (due July 29, 2026) solicited chemical supply on a unit-cost basis for municipal water treatment. The code shows sparse recent activity across a fragmented issuing-body base with no dominant repeat buyer, suggesting opportunistic tagging of diverse chemical and equipment procurements rather than a coherent commodity family under active, sustained procurement.
