UNSPSC 51191958: Thiamine tetrahydrofurfuryl disulfide hydrochloride

This classification denotes a b vitamin with the molecular formula C17H26N4O3S2.ClH, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier T3557LWB27, chemically known as n-((4-amino-2-methylpyrimidin-5-yl)methyl)-n-((1e)-4-hydroxy-1-methyl-2-((tetrahydrofuran-2-ylmethyl)disulfanyl)but-1-en-1-yl)formamide hydrochloride, but more generally known as thiamine tetrahydrofurfuryl disulfide hydrochloride, which bears US NIH Compound Identifier 3036228.

European Medicines Agency schedules thiamine tetrahydrofurfuryl disulfide hydrochloride or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10969MIG. Most nations, for tariff purposes, schedule thiamine tetrahydrofurfuryl disulfide hydrochloride under HS 29362200. SMILES: CC1NCC(C(N1)N)CN(C=O)/C(=C(\CCO)/SSCC2CCCO2)/C.CL.

UNSPSC 51191958 Thiamine tetrahydrofurfuryl disulfide hydrochloride is a Commodity code that does not align with the state and local procurement activity tagged under it. The three most recent opportunities posting under this code involve DeZurik/APCO valve parts and repair services for wastewater treatment (Broward County, Florida), parenteral nutrition and intravenous products for correctional healthcare (Washington State Department of Corrections), and sodium bisulfite chemical supply for municipal water treatment (City of Meriden, Connecticut). None of these solicitations concern thiamine tetrahydrofurfuryl disulfide hydrochloride or pharmaceutical thiamine products; the code assignment appears to reflect a taxonomy mismatch rather than active procurement of the commodity the code nominally describes.

Recent activity shows issuing bodies spanning county departments (Broward County purchasing), state corrections agencies (Washington DOC), and municipal utilities (City of Meriden water department). The geographic footprint includes Florida, Washington state, and Connecticut. The Broward County RFI (BLD6232026F23, due September 29, 2026) sought confirmation of authorized suppliers and capability for DeZurik valve maintenance and SCADA-compatible repair services in a wastewater environment. The Washington State Department of Corrections RFQ (RFQQK13020, due October 7, 2026) solicited parenteral nutrition solutions, intravenous products, and controlled substances for eight correctional facilities across three regions, with pre-bid conference on September 23, 2026 and contract award targeting multiple vendors per region. The City of Meriden IFB (B027-15, due July 29, 2026) sought sodium bisulfite chemical supply for water pollution control operations. The code shows no recent procurement activity aligned with its stated pharmaceutical content, and business development professionals should verify the correct code assignment before pursuing opportunities under this classification.
