UNSPSC 51191508: Triamterene

This classification denotes a potassium-sparing diuretic with the molecular formula C12H11N7, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier WS821Z52LQ, chemically known as 2,4,7-triamino-6-phenylpteridine but generally known as triamterene, which bears US NIH Compound Identifier 5546. European Medicines Agency schedules Triamterene in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11256MIG. The term TRIAMTERENE is an International Non-Proprietary Name.

UNSPSC 51191508 Triamterene is a Commodity code for a specific pharmaceutical product, but the recent state and local contract opportunities posted under this code do not involve triamterene procurement. Instead, the opportunities span parenteral nutrition and intravenous solutions for a corrections health system, wastewater treatment valve parts and repair services, and sodium bisulfite chemical supply for municipal water treatment. The mismatch suggests that state and local jurisdictions are tagging unrelated commodity purchases with this code, or the code classification in the source material does not reflect the actual scope of work. State and local solicitations under this code classification do not currently pursue triamterene supply or pharmaceutical procurement aligned with the code's nominal scope.

The Washington State Department of Corrections, the City of Meriden, and Broward County, Florida have posted the three most recent opportunities. The DOC's parenteral products RFQ (RFQQK13020, due October 7, 2026) seeks parenteral nutrition, intravenous solutions, and controlled substances for eight correctional facilities across three regions, with pre-bid conference on September 23, 2026 and aspirational set-asides for small business (25%), minority-owned business (10%), women-owned business (6%), and veteran-owned business (5%). The City of Meriden issued an IFB for sodium bisulfite supply (B027-15, due July 29, 2026) for its Water Pollution Control Facility. Broward County posted an RFI (BLD6232026F23, due September 29, 2026) to identify alternative suppliers or products for DeZurik/APCO valves and SCADA-compatible repair services for wastewater treatment operations currently sole-sourced to Controls Specialties, Inc. Buying bodies are limited to state corrections, single municipalities, and county water/wastewater departments in Florida, Connecticut, and Washington. No standout repeat buyers appear in the recent record.
