UNSPSC 51284131: Cefixime trihydrate

This classification denotes a cephalosporin antibiotic with the molecular formula C16H15N5O7S2.3H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 97I1C92E55, chemically known as 5-thia-1-azabicyclo(4.2.0)oct-2-ene-2-carboxylic acid, 7-(((2-amino-4-thiazolyl)((carboxymethoxy)imino)acetyl)amino)-3-ethenyl-8-oxo-, trihydrate, (6r-(6.alpha.,7.beta.(z)))-, but more generally known as cefixime trihydrate, which bears US NIH Compound Identifier 6321411.

European Medicines Agency schedules cefixime trihydrate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07395MIG. Most nations, for tariff purposes, schedule cefixime trihydrate under HS 29419000. SMILES: C=CC1=C(N2[C@@H]([C@@H](C2=O)NC(=O)/C(=N\OCC(=O)O)/C3CSC(N3)N)SC1)C(=O)O.O.O.O.

UNSPSC 51284131 Cefixime trihydrate, a Commodity code, shows minimal relevant recent activity among state and local purchasers. The code nominally identifies a specific antibiotic product, yet the recent opportunities posted under this code procure naloxone and drug deactivation systems, medical and first aid supplies for emergency response, generic multi-source pharmaceuticals through cooperative purchasing, and direct-to-manufacturer prescription programs—none of which involve cefixime. This mismatch between the code's nominal scope and the actual work being bought suggests either miscoding in source databases or that cefixime procurement does not currently drive significant state and local solicitation volume. State and local health departments, fire-rescue divisions, and cooperative purchasing alliances posting under this code appear focused on broader pharmaceutical and medical supply categories rather than individual antibiotic line items.

The geographic spread of opportunities is limited. Recent solicitations come from Seminole County, Florida; the City of Tampa, Florida; the Texas Health and Human Services Commission; and the Minnesota Multistate Cooperative Purchasing Alliance serving multiple states including Oregon. The Tampa Fire Department RFQ for medical and first aid supplies (ITB 26P00145, due March 13, 2026) represents the most directly relevant to emergency medical procurement, while the MMCAP RFP for generic multi-source pharmaceuticals (S1070000015802, due March 26, 2026) shows cooperative purchasing scale across state and local health systems. No recent solicitations specifically target cefixime procurement, and the code shows little signal of active procurement interest in its nominal product category within the current state and local marketplace.
