UNSPSC 51381901: Ebselen

This classification denotes a cyclooxygenase inhibitor and antioxidant with the molecular formula C13H9NOSe, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 40X2P7DPGH, chemically known as 1,2-benzisoselenazol-3(2h)-one, 2-phenyl- but generally known as ebselen, which bears US NIH Compound Identifier 3194. European Medicines Agency schedules Ebselen in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06439MIG.

UNSPSC 51381901 Ebselen is a Commodity code, but state and local governments are not soliciting ebselen itself under this code. The recent opportunity tagged to it—Seminole County, Florida's IFB 60459723LAS, posted June 30, 2026, with a response deadline of July 26, 2023—calls for naloxone and safe drug deactivation systems for community health support, not ebselen. The mismatch between the code's chemical name and the actual procurement scope suggests either a data-entry error in the county's tagging or a state and local taxonomy that diverges significantly from the UNSPSC standard. The code shows minimal relevant recent activity aligned to its nominal scope.

Without additional recent opportunities properly tagged to UNSPSC 51381901, no reliable characterization of issuing-body mix, geographic spread, or representative solicitation activity under the code is possible. The single tagged opportunity is a two-year county health procurement with a one-year renewal option, requiring quarterly deliveries, E-Verify compliance, and FEMA-compliance riders, but it does not represent ebselen purchasing. Firms evaluating this code should verify directly with state and local procurement offices or cooperative-purchasing consortia whether ebselen is procured under a different code or remains inactive in state and local markets.
