UNSPSC 51191938: Thiamine disulfide nitrate

This classification denotes a b vitamin C24H34N8O4S2.2HNO3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 0Z281VOQ5O, chemically known as formamide, n,n'-(dithiobis(2-(2-hydroxyethyl)-1-methyl-2,1-ethenediyl))bis(n-((4-amino-2-methyl-5-pyrimidinyl)methyl)-, (z,z)-, dinitrate (salt), but more generally known as thiamine disulfide nitrate, which bears US NIH Compound Identifier 44630506. Most nations, for tariff and trade purposes, schedule thiamine disulfide nitrate under HS 29362200 and SITC 54113.

As of Q4 2014, THIAMINE DISULFIDE NITRATE 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)/CCO)/CCO)/C)C=O)N.[N+](=O)([O-])O.[N+](=O)([O-])O.

UNSPSC 51191938 Thiamine disulfide nitrate is a Commodity code that state and local governments use to procure specialized pharmaceutical and chemical products for healthcare, correctional, and water treatment operations. Recent activity shows no direct procurement of thiamine disulfide nitrate; instead, the code has been applied to solicitations for unrelated commodities—parenteral nutrition and intravenous solutions for correctional healthcare, sodium bisulfite for municipal water treatment, and valve repair services for wastewater systems. The mismatch between the code's nominal scope (a specific B-vitamin compound) and the actual work being purchased suggests the code sees little relevant recent activity in state and local procurement, or that issuing bodies are tagging diverse chemical and pharmaceutical products under an overly narrow category.

The three recent opportunities in the block span Washington State, Florida, and Connecticut, representing corrections departments, municipal water utilities, and county environmental services rather than a coherent buyer base for thiamine disulfide nitrate. The Washington State Department of Corrections issued an RFQ for parenteral products with responses due October 7, 2026; Broward County, Florida issued an RFI on valve repair services due September 29, 2026; and the City of Meriden, Connecticut issued an IFB for sodium bisulfite due July 29, 2026. No solicitation in the block targets the stated commodity itself, and no pattern of repeat demand for thiamine disulfide nitrate emerges from recent state and local posting activity.
