UNSPSC 51191502: Chlortalidone or chlorthalidone

This classification denotes a thiazide diuretic with the molecular formula C14H11ClN2O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier Q0MQD1073Q, chemically known as 2-chloro-5-(2,3-dihydro-1-hydroxy-3-oxo-1h-isoindol-1-yl)benzenesulfonamide but generally known as chlortalidone, which bears US NIH Compound Identifier 2732. European Medicines Agency schedules Chlortalidone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06212MIG.

UNSPSC 51191502 Chlortalidone or chlorthalidone, a Commodity code, shows limited alignment between its nominal pharmaceutical scope and recent state and local solicitations. The code appears in procurement records for pharmaceutical and medical products, but the recent opportunities posted under this code do not involve chlortalidone or related diuretic medications. Instead, state and local issuing bodies are using this code designation for industrial chemicals, water treatment supplies, and medical equipment that fall outside the chlortalidone category — including valve components for wastewater treatment, parenteral nutrition and intravenous solutions, and sodium bisulfite chemical supply. This mismatch signals either inconsistent code assignment by issuing offices or a data classification issue within the procurement system.

Recent activity spans three states with distinct purchasing contexts: Broward County, Florida issued a Request for Information on DeZurik/APCO valves and repair services for wastewater facility compliance (due September 29, 2026); the Washington State Department of Corrections issued an RFQ for parenteral products, services, and equipment for eight correctional facilities across Washington (due October 7, 2026, with a pre-bid conference on September 23, 2026 and aspirational small and diverse business participation targets including MBE, WBE, and VBE); and the City of Meriden, Connecticut issued an IFB for sodium bisulfite chemical supply for its Water Pollution Control Facility (due July 29, 2026). The code shows limited relevant recent activity for businesses positioned to supply chlortalidone or comparable antihypertensive medications to state and local health departments, correctional systems, or municipal health agencies. Practitioners should verify code assignment in RFP or RFQ documents before pursuing opportunities tagged under this code, as the mismatch between the code's stated scope and actual commodity being procured suggests potential classification errors.
