UNSPSC 51191548: Fenquizone

This classification denotes a thiazide diuretic with the molecular formula C14H12ClN3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier LJ1U13R8IK, chemically known as 6-quinazolinesulfonamide, 7-chloro-1,2,3,4-tetrahydro-4-oxo-2-phenyl-, (+-)- but generally known as fenquizone, which bears US NIH Compound Identifier 68548. European Medicines Agency schedules Fenquizone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07594MIG.

UNSPSC 51191548 Fenquizone is a Commodity code that in practice covers chemical supply for municipal water treatment and pollution control operations, though recent state and local solicitations under this code tag show limited direct fenquizone procurement — the most recent opportunity names sodium bisulfite as the primary chemical commodity. State and local water authorities and municipal utilities use this code family to solicit treatment chemicals for drinking water and wastewater facilities. Issuing bodies include municipal departments of public works and water pollution control authorities, which procure chemicals on an as-needed basis under firm-pricing contracts with insurance and bonding requirements typical of municipal infrastructure operations.

The City of Meriden posted an IFB for sodium bisulfite supply to its Water Pollution Control Facility with bids due July 29, 2026 (solicitation B027-15), requiring bidders to carry $1 million to $2 million in general liability coverage, a performance bond, and a labor and material payment bond. Activity under this code appears concentrated among Connecticut municipalities and water authorities, though the source does not support a broader geographic characterization. A separate RFP posted by the Minnesota Multistate Cooperative Purchasing Alliance in January 2026 for generic pharmaceuticals and OTC products was tagged with this code but shows no meaningful connection to fenquizone or water-treatment chemistry — this mismatch suggests inconsistent coding across state procurement systems and limits confidence in the code's actual buying pattern from the source provided.
