UNSPSC 51191501: Chlorothiazide

This classification denotes a thiazide diuretic with the molecular formula C7H6ClN3O4S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 77W477J15H, chemically known as 6-chloro-7-sulfamoyl-2h-1,2,4-benzothiadiazine 1,1-dioxide but generally known as chlorothiazide, which bears US NIH Compound Identifier 2720. European Medicines Agency schedules Chlorothiazide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06198MIG.

UNSPSC 51191501 Chlorothiazide is a Commodity code that captures pharmaceuticals and related chemical compounds procured by state and local government entities for medical, water treatment, and operational use. The recent opportunities posted under this code show a divergence: one solicitation targets sodium bisulfite, a water-treatment chemical unrelated to the code's pharmaceutical scope, while the other targets generic multi-source pharmaceuticals and over-the-counter products distributed through state and local healthcare facilities. State and local buyers under the pharmaceutical focus include cooperative purchasing alliances, state departments of administration, and municipal water and health agencies. The scope when aligned with the code's intent covers generic pharmaceuticals and OTC products supplied through authorized wholesalers to participating government healthcare systems, with vendors required to manage pricing through National Drug Code submissions, comply with current Good Manufacturing Practices and Drug Supply Chain Security Act requirements, and maintain contractual relationships with established pharmaceutical wholesalers.

Recent activity reflects two distinct procurement models across different issuing bodies. 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 (due March 26, 2026) to establish multi-award contracts for generic pharmaceuticals and OTC products distributed across participating state and local government facilities including Oregon, with contract term of two years and optional extensions, evaluated 75 percent on price competitiveness and 25 percent on administrative compliance, EDI capability, and pricing format options. The City of Meriden, Connecticut issued an IFB (solicitation B027-15) on July 8, 2026 (due July 29, 2026) for sodium bisulfite chemical supply for its Water Pollution Control Facility, a scope outside the code's pharmaceutical intent. Geographic activity appears concentrated in the Upper Midwest and Northeast, with MMCAP covering multiple states and the Connecticut municipal opportunity suggesting regional distribution. The code shows limited and narrowly targeted recent activity; the pharmaceutical-focused solicitation represents the more relevant recent procurement signal.
