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 specialty chemical products for water treatment, pharmaceutical supply, and related operational needs. Recent solicitations show the code capturing both narrowly specified inorganic chemicals for municipal water facilities and broader pharmaceutical and over-the-counter product procurement where chemical compounds are listed as line items. State and local issuing bodies soliciting under this code span municipalities (city water departments), state cooperative purchasing alliances, and multi-jurisdiction consortia administering statewide health and operations contracts. The City of Meriden, Connecticut, and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) are recent active buyers; MMCAP's scope extends across participating state and local government facilities including Oregon.

Activity under the code appears concentrated in the Northeast and Upper Midwest. The City of Meriden issued an IFB for sodium bisulfite (solicitation B027-15) due July 29, 2026, for chemical supply to its Water Pollution Control Facility, with unit-cost pricing evaluation and performance and payment bond requirements. MMCAP issued an RFP (S1070000015802) due March 26, 2026, to establish multi-vendor contracts for generic pharmaceuticals and OTC products distributed across participating jurisdictions, with pricing weighted at 75 percent and compliance, EDI capability, and administrative fee structure at 20 percent combined; the contract is effective July 1, 2026, for two years. Both opportunities require standard commercial insurance (general liability, workers' compensation) and demonstrate the code's application across chemical operations and pharmaceutical supply chains serving public health and municipal infrastructure.
