UNSPSC 51191528: Althiazide or altizide

This classification denotes a thiazide diuretic with the molecular formula C11H14ClN3O4S3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier GI8CB72B0D, chemically known as 6-chloro-3,4-dihydro-3-((2-propenylthio)methyl)-2h-1,2,4-benzothiadiazine-7-sulfonamide but generally known as althiazide, which bears US NIH Compound Identifier 2122. European Medicines Agency schedules Althiazide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05379MIG.

Althiazide or altizide bears US NLM identifiers UMLS ID C0051500 and NCI Concept Code C80838. SMILES: C=CCSCC1NC2=CC(=C(C=C2S(=O)(=O)N1)S(=O)(=O)N)CL.

UNSPSC 51191528 Althiazide or altizide is a Commodity code that shows minimal alignment with recent state and local procurement activity. The code nominally identifies a specific thiazide diuretic pharmaceutical compound, yet the two most recent opportunities posted under this code involve sodium bisulfite (a water-treatment chemical) and generic multi-source pharmaceuticals and OTC products — neither of which is althiazide. The mismatch suggests either a tagging error in the underlying procurement database or that this code is used inconsistently across jurisdictions for pharmaceutical and chemical purchases that do not match its narrow definition.

The recent activity that does appear comes from disparate issuing bodies and geographies. The City of Meriden, Connecticut posted an IFB for sodium bisulfite chemical supply to its Water Pollution Control Facility with bids due July 29, 2026 (Solicitation B027-15). The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP on January 20, 2026 for generic multi-source pharmaceuticals and OTC products, with proposals due March 26, 2026, to serve participating state and local government facilities across multiple states including Oregon. Neither opportunity is germane to althiazide procurement, and no recent solicitations specifically targeting this or similar thiazide diuretics appear in the dataset. The code shows little substantive recent activity and does not reflect genuine state and local demand for the commodity it nominally describes.
