UNSPSC 51343602: Methisazone or metisazone

This classification denotes an antiviral agent with the molecular formula C10H10N4OS, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier K3QML4J07E, chemically known as 1-methylindole-2,3-dione 3-(thiosemicarbazone) but generally known as methisazone, which bears US NIH Compound Identifier 6861563. European Medicines Agency schedules Metisazone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08895MIG. The term METHISAZONE is an International Non-Proprietary Name.

World Health Organization schedules methisazone in its Anatomical Therapeutic Chemical (ATC) Classification. Methisazone or metisazone bears US NLM identifiers UMLS ID C0025656 and NCI Concept Code C77928. SMILES: CN1C2=CC=CC=C2C(=NNC(=S)N)C1=O.

UNSPSC 51343602 Methisazone or metisazone, a Commodity code, shows minimal alignment between its nominal scope and actual state and local procurement activity. The recent opportunities posted under this code do not involve methisazone or metisazone procurement; instead, they reflect purchases of naloxone, medical and first aid supplies, generic pharmaceuticals and OTC products, and exploration of direct-to-manufacturer prescription programs. The code appears to be a catchall or misclassification placeholder for broader pharmaceutical and medical supply sourcing, rather than a dedicated track for the specific antivirotical compound named in the code's taxonomy. Issuing bodies soliciting under this classification include county health departments, municipal fire services, state health and human services commissions, and cooperative purchasing alliances serving multistate public sector networks.

Activity spans Florida, Texas, Minnesota, and participating cooperative jurisdictions. The most recent posted opportunities include Seminole County, Florida's IFB 60459723LAS (due July 26, 2023) seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually; the City of Tampa's sealed bid 26P00145 (due March 13, 2026) for 169 line items of medical and first aid supplies for the Tampa Fire Department Rescue Division, with an estimated contract value of $700,000 and a sheltered-market small local business enterprise set-aside; the Minnesota Multistate Cooperative Purchasing Alliance's RFP S1070000015802 (due March 26, 2026) establishing multiple contracts for generic pharmaceuticals and OTC products distributed through authorized wholesalers to participating state and local facilities; and the Texas Health and Human Services Commission's RFI HHS0017013 (due April 3, 2026) exploring direct-to-manufacturer prescription programs. The code's sparse thematic coherence and mismatch between its nominal scope and posted work suggest limited relevance for vendors focused on methisazone or narrow antiviral therapeutics.
