UNSPSC 51191956: Thiamine pyrophosphate chloride

This classification denotes a b vitamin with the molecular formula C12H19N4O7P2S.Cl, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier XMK8K8EVIU, chemically known as thiazolium, 3-((4-amino-2-methyl-5-pyrimidinyl)methyl)-4-methyl-5-(4,6,6-trihydroxy-4,6-dioxido-3,5-dioxa-4,6-diphosphahex-1-yl)-, chloride (1:1), but more generally known as thiamine pyrophosphate chloride, which bears US NIH Compound Identifier 9068.

European Medicines Agency schedules thiamine pyrophosphate chloride or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10969MIG. Most nations, for tariff purposes, schedule thiamine pyrophosphate chloride under HS 29362200. SMILES: CC1C(SC[N+]1CC2CNC(NC2N)C)CCOP(=O)(O)OP(=O)(O)O.[CL-].

UNSPSC 51191956 Thiamine pyrophosphate chloride is a Commodity code that nominally describes a specific B-vitamin compound, but the recent state and local opportunities tagged to this code show minimal alignment with that scope. The three most recent solicitations under the code involve wastewater treatment valve parts and repair services (Broward County, Florida), parenteral nutrition and intravenous solutions for correctional health care (Washington State Department of Corrections), and sodium bisulfite chemical supply for municipal water treatment (City of Meriden, Connecticut). The issuing bodies are a county government, a state corrections department, and a municipality — spanning water and wastewater infrastructure, health care delivery, and chemical supply procurement. None of these opportunities involve thiamine pyrophosphate chloride or pharmaceutical-grade vitamins in the manner the code name suggests.

The geographic spread is sparse and geographically scattered: Florida, Washington, and Connecticut. The Broward County RFI (BLD6232026F23, due September 29, 2026) sought alternative suppliers for DeZurik/APCO valves with SCADA compatibility for wastewater compliance. The Washington State Department of Corrections RFQ (RFQQK13020, due October 7, 2026) solicited parenteral nutrition and intravenous solutions for eight correctional facilities across three regions, with pre-bid conference on September 23, 2026 and multiple regional awards anticipated through June 30, 2030. The City of Meriden IFB (B027-15, due July 29, 2026) solicited sodium bisulfite for its Water Pollution Control Facility. This code shows little relevant recent activity in its stated scope; the opportunities present suggest a tagging mismatch rather than active procurement of thiamine pyrophosphate chloride in state and local markets.
