UNSPSC 51191503: Metolazone

This classification denotes a thiazide diuretic with the molecular formula C16H16ClN3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier TZ7V40X7VX, chemically known as 7-chloro-2-methyl-3-(2-methylphenyl)-4-oxo-1,2-dihydroquinazoline-6-sulfonamide but generally known as metolazone, which bears US NIH Compound Identifier 4170. European Medicines Agency schedules Metolazone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08906MIG.

UNSPSC 51191503 Metolazone is a Commodity code that does not map to the recent state and local opportunities tagged under it. The three most recent solicitations involve wastewater control valves and parts (Broward County), parenteral pharmaceutical products and IV solutions (Washington State Department of Corrections), and sodium bisulfite chemical supply (City of Meriden). None of these commodities is metolazone, a diuretic pharmaceutical. The tagging mismatch suggests either a cataloging error in the source system or a scope that diverges significantly from the code's nominal pharmaceutical definition. State and local procurement activity under this code shows little relevant recent volume.

Without substantive opportunities directly matching the code's stated scope, a pursue decision would require confirmation that the issuing bodies' internal taxonomies align with UNSPSC definitions and that metolazone procurement is indeed active at the state or local level. Watch this code if your firm supplies pharmaceutical products to correctional facilities, water authorities, or health agencies — the Washington DOC parenteral-products RFQ (RFQQK13020, due October 7, 2026) demonstrates that state corrections systems do solicit pharmaceutical supplies through formal competitive bids with multi-region contracting and small-business aspirational goals, even if metolazone specifically is not present in this cycle.
