UNSPSC 51283913: Sulfametoxydiazine or sulfamethoxydiazine sulfameter

This classification denotes a sulfonamide anti-infective agent with the molecular formula C11H12N4O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3L179F09D6, chemically known as sulfanilamide, n(sup 1)-(5-methoxy-2-pyrimidinyl)- but generally known as sulfameter, which bears US NIH Compound Identifier 5326. European Medicines Agency schedules Sulfametoxydiazine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10714MIG.

The term SULFAMETOXYDIAZINE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 21 No. 12 1967, List 7). World Health Organization schedules sulfameter in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: COC1=CN=C(N=C1)NS(=O)(=O)C2=CC=C(C=C2)N.

UNSPSC 51283913 Sulfametoxydiazine or sulfamethoxydiazine sulfameter is a Commodity code that covers specific antibiotic and pharmaceutical active ingredients used in state and local health procurement, though recent opportunities tagged under this code show limited direct relevance to the nominal scope. The Illinois Department of Public Health and Seminole County, Florida have issued recent pharmaceutical-related procurements that were tagged with this code, but neither solicitation concerns sulfametoxydiazine compounds. Instead, the Illinois Department of Public Health awarded a $2,999,999.11 piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets, while Seminole County issued an IFB in June 2026 for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually. Both are state and local health agencies procuring pharmaceutical products through standard competitive bidding, but the products themselves fall outside the sulfametoxydiazine family. The Illinois award was completed under an IFB process with a 12-month initial term and renewal options through year three; Seminole County's procurement required quarterly deliveries with a two-year initial term and one-year renewal option, and included FEMA funding with associated federal compliance requirements.

Recent activity under this code occurs in Illinois and Florida, though the mismatch between the code's nominal scope and the actual products being solicited suggests that the code may be misapplied in current state and local procurement systems or that sulfametoxydiazine compounds see minimal direct procurement activity at the state and local level. No open solicitations for sulfametoxydiazine itself appear in the source material; the two opportunities listed are completed awards or historic notices for unrelated pharmaceutical products.
