UNSPSC 51332860: Metofenazate difumarate

This classification denotes a phenothiazine with the molecular formula C31H36ClN3O5S.2C4H4O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2A3RCX7T4J, chemically known as benzoic acid, 3,4,5-trimethoxy-, 2-(4-(3-(2-chloro-10h-phenothiazin-10-yl)propyl)-1-piperazinyl)ethyl ester, (2e)-2-butenedioate (1:2), but more generally known as metofenazate difumarate, which bears US NIH Compound Identifier 6433198.

European Medicines Agency schedules metofenazate difumarate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08903MIG. Most nations, for tariff purposes, schedule metofenazate difumarate under HS 29343090. SMILES: COC1C(C(CC(C1)C(=O)OCCN2CCN(CC2)CCCN3C4C(CCC(C4)CL)SC5C3CCCC5)OC)OC.C(=C/C(=O)O)\C(=O)O.C(=C/C(=O)O)\C(=O)O.

UNSPSC 51332860 Metofenazate difumarate is a Commodity code that bears little relevance to recent state and local procurement activity posted under it. The sole recent opportunity tagged with this code—Seminole County, Florida's IFB60459723LAS—solicits naloxone and drug deactivation systems for community health initiatives, a scope unrelated to metofenazate difumarate, an insecticide used in agricultural and veterinary applications. The mismatch suggests either a data-entry error in the county's procurement system or an outlier misclassification. State and local governments do not appear to be actively procuring metofenazate difumarate under this code at present.

The single opportunity on record—Seminole County's IFB posted June 30, 2026, with a response deadline of July 26, 2023—requests 1,900 units of naloxone and 800 safe drug deactivation systems annually, delivered quarterly to the Seminole County Community Health Building in Sanford, Florida. Vendors must include shipping and delivery costs in their bids, comply with E-Verify and drug-free workplace requirements, and maintain workers' compensation and liability insurance. The contract term is two years with an optional one-year renewal and includes a three-month probationary termination clause. This is a public-health-focused procurement that does not align with the code's nominal chemical substance scope. No additional state or local opportunities under this code are evident in the recent record.
