UNSPSC 51191506: Amiloride

This classification denotes a potassium-sparing diuretic and intercalating agent with the molecular formula C6H8ClN7O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 7DZO8EB0Z3, chemically known as 3,5-diamino-n-(aminoiminomethyl)-6-chloropyrazinecarboxamide but generally known as amiloride, which bears US NIH Compound Identifier 16231. Amiloride most often comes in caproate, chloride, hydrochloride, hydrochloride dihydrate, and hydrochloride-hydrochlorothiazide forms.

UNSPSC 51191506 Amiloride, a Commodity code, does not reflect the work actually being solicited under it in recent state and local opportunities. The three recent postings tagged to this code procure wastewater and water treatment chemicals (sodium bisulfite for municipal pollution control), parenteral nutrition and intravenous products for correctional healthcare, and specialized valve components for wastewater systems — none of which are amiloride, a potassium-sparing diuretic pharmaceutical. The code appears to be a taxonomy mismatch across the issuing bodies rather than an active procurement category for the drug itself.

State and local opportunities under this code tag come from water and wastewater authorities, corrections departments, and county purchasing offices. The Washington State Department of Corrections issued an RFQ (due October 7, 2026) for parenteral products, services, and equipment to eight correctional facilities statewide, with DOC anticipating multiple awards across three regions and a contract term through June 30, 2030. Broward County, Florida posted an RFI (due September 29, 2026) on DeZurik/APCO valves and repair services for wastewater compliance, and the City of Meriden, Connecticut solicited bids for sodium bisulfite chemical supply for its Water Pollution Control Facility (due July 29, 2026). Geographic activity spans Florida, Washington State, and Connecticut. The code shows recent posting activity but no direct pharmaceutical procurement aligned with amiloride or other diuretic drugs; the tagging appears incidental rather than indicative of an open market for this commodity under this UNSPSC classification.
