UNSPSC 51141521: Mesuximide or methsuximide

This classification denotes an anticonvulsant agent with the molecular formula C12H13NO2, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier 0G76K8X6C0, chemically known as 2,5-pyrrolidinedione,1,3-dimethyl-3-phenyl- but more generally known as mesuximide, which bears US NIH Compound Identifier 6476. European Medicines Agency schedules Mesuximide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08797MIG.

UNSPSC 51141521 Mesuximide or methsuximide, a Commodity code, shows minimal recent alignment with the code's nominal pharmaceutical scope in state and local procurement activity. The single recent opportunity posted under this code — Seminole County, Florida's IFB 60459723LAS — solicits Naloxone and Safe Drug Deactivation Systems, products entirely outside the anticonvulsant medication family the code nominally describes. The mismatch suggests either a tagging error in the source data or a jurisdictional classification practice that does not align with UNSPSC intent. State and local procurement offices issuing under this code appear limited to health and human services departments and county public health agencies where the source supports visibility.

The recent activity concentrates in Florida, specifically Seminole County. The IFB posted June 30, 2026, with a response deadline of July 26, 2023 (a date inconsistency in the source record), calls for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford. Vendors must submit bids electronically, include all shipping and delivery costs, comply with drug-free workplace and E-Verify requirements, maintain specified insurance coverages, and accept a three-month probationary termination clause. The contract carries a two-year initial term with a one-year renewal option and potential FEMA funding, introducing federal compliance obligations. No explicit set-aside designations were noted. Given the code's limited recent posting volume and the mismatch between the nominal commodity and actual procurement activity, the code presents a narrow and uncertain opportunity landscape for pursuit.
