UNSPSC 51191954: Thiamine propyl disulfide

This classification denotes a b vitamin with the molecular formula C15H24N4O2S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier UI32MM3XE3, chemically known as n-((4-amino-2-methyl-5-pyrimidinyl)methyl)-n-(4-hydroxy-1-methyl-2-(propyldithio)-1-butenyl)formamide, but more generally known as thiamine propyl disulfide, which bears US NIH Compound Identifier 4963. European Medicines Agency schedules thiamine propyl disulfide or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10969MIG.

Most nations, for tariff purposes, schedule thiamine propyl disulfide under HS 29362200. SMILES: CCCSS/C(=C(\C)/N(CC1CNC(NC1N)C)C=O)/CCO.

UNSPSC 51191954 Thiamine propyl disulfide is a Commodity code that shows sparse recent state and local procurement activity. The three posted opportunities tagged under this code — a Broward County valve-parts RFI, a Washington State Department of Corrections parenteral-products RFQQ, and a City of Meriden sodium-bisulfite IFB — do not align with thiamine propyl disulfide, a pharmaceutical or nutritional supplement ingredient. The mismatch suggests either miscoding by issuing bodies or that the code rarely maps to actual state and local buys. No recent opportunity explicitly solicits thiamine propyl disulfide as a supply item.

Without concrete evidence of active demand for thiamine propyl disulfide in state and local procurement, the code presents minimal business-development signals. Firms serving this market should monitor whether state corrections, public-health departments, or water-treatment authorities post targeted opportunities, but current activity does not support a pursue recommendation based on recent RFI, RFQ, IFB, or ITB records.
