UNSPSC 51191564: Quinethazone

This classification denotes a thiazide diuretic with the molecular formula C10H12ClN3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 455E0S048W, chemically known as 7-chloro-2-ethyl-6-sulfamoyl-1,2,3,4-tetrahydro-4-quinazolinone but generally known as quinethazone, which bears US NIH Compound Identifier 6307. European Medicines Agency schedules Quinethazone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10213MIG.

UNSPSC 51191564 Quinethazone, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal scope. The code ostensibly covers quinethazone, a specific chemical compound, but recent opportunities tagged to this code do not reflect purchases of that substance. Instead, the City of Meriden (Connecticut) posted an IFB for sodium bisulfite chemical supply for water treatment operations at its Water Pollution Control Facility, due July 29, 2026—a different chemical commodity used in municipal water pollution control. A second opportunity, the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP for generic multi-source pharmaceuticals and over-the-counter products with a March 26, 2026 due date, involves pharmaceutical manufacturing and distribution, not chemical treatment supplies. The mismatch between the code's stated chemical and what municipalities are actually buying suggests either sparse activity in quinethazone procurement at the state and local level or systematic misclassification of solicitations in the underlying database.

Activity under this code spans Connecticut and Minnesota-led cooperative purchasing, though the pharmaceutical RFP extends across multiple participating states including Oregon. No recent opportunities directly solicit quinethazone itself. The water treatment chemical bid from Meriden represents municipal utility procurement, while the MMCAP pharmaceutical contract represents cooperative purchasing through a state procurement office. Given the absence of relevant quinethazone-specific opportunities and the clear mismatch between the code's scope and actual posted work, this code warrants monitoring rather than active pursuit at present; the opportunity pipeline does not currently support a focused business strategy around quinethazone supply to state and local buyers.
