UNSPSC 51283953: Sulfaquinoxaline sodium

This classification denotes a sulfonamide anti-infective agent with the molecular formula C14H11N4O2S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 21223EPJ40, chemically known as n1-(quinoxalin-2-yl)sulphanilamide sodium salt, but more generally known as sulfaquinoxaline sodium, which bears US NIH Compound Identifier 71594. European Medicines Agency schedules sulfaquinoxaline sodium or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10725MIG.

Most nations, for tariff purposes, schedule sulfaquinoxaline sodium under HS 29350090. Sulfaquinoxaline sodium bears US NLM identifiers UMLS ID C2728210 and NCI Concept Code C90992. SMILES: C1CCC2C(C1)NCC(N2)[N-]S(=O)(=O)C3CCC(CC3)N.[NA+].

UNSPSC 51283953 Sulfaquinoxaline sodium is a Commodity code that represents a specific veterinary pharmaceutical product, yet recent state and local contract opportunities posted under this code do not align with its nominal scope. The opportunities on record solicit naloxone and drug deactivation systems, prescription fulfillment programs, emergency medical and first aid supplies, and generic pharmaceuticals and OTC products—none of which are sulfaquinoxaline sodium or veterinary pharmaceuticals. This mismatch suggests either broad tagging by issuing bodies or a systematic misclassification of these procurements within state and local procurement systems. The actual work being solicited under this code tag spans human-health pharmaceuticals, emergency medical supplies, and pharmacy benefit program administration rather than veterinary therapeutics.

Recent activity shows issuing bodies across multiple jurisdictional types. Seminole County, Florida issued an IFB for naloxone and drug deactivation systems (1,900 units of naloxone and 800 deactivation systems annually, due July 26, 2023); the City of Tampa's Fire Department issued an ITB for medical and first aid supplies comprising 169 line items with an estimated contract value of $700,000 (due March 13, 2026, designated as a sheltered market for certified Small Local Business Enterprises); the Minnesota Multistate Cooperative Purchasing Alliance issued an RFP for generic multi-source pharmaceuticals and OTC products to serve participating state and local facilities in Minnesota and Oregon (due March 26, 2026); and the Texas Health and Human Services Commission issued an RFI on direct-to-manufacturer prescription programs (due April 3, 2026). Activity clusters in Florida, Texas, and the Upper Midwest, driven by health department, fire department, and cooperative purchasing vehicles. The code shows marginal relevance to the UNSPSC nominal definition and presents limited pursuit value unless your firm works in pharmaceutical distribution or emergency medical supplies and can clarify the actual procurement classification with issuing bodies prior to bid.
