UNSPSC 51282401: Amdinocillin or mecillinam

This classification denotes a penicillin antibiotic with the molecular formula C15H23N3O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier V10579P3QZ, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 6-(((hexahydro-1h-azepin-1-yl)methylene)amino)-3,3-dimethyl-7-oxo-, (2,2-dimethyl-1-oxopropoxy)methyl ester, (2s-(2alpha,5alpha,6beta))- but generally known as amdinocillin, which bears US NIH Compound Identifier 36272. Amdinocillin most often comes in mecillinam and pivoxil forms.

UNSPSC 51282401 Amdinocillin or mecillinam is a Commodity code that shows minimal alignment with recent state and local procurement activity. The code nominally designates a specific antibiotic pharmaceutical product, but the recent opportunities posted under it span naloxone procurement, direct-to-manufacturer pharmacy programs, emergency medical supplies, and multi-source generic pharmaceuticals—none of which involve amdinocillin or mecillinam. The mismatch between the code's scope and what state and local buyers are actually soliciting suggests either a cataloging error in how opportunities are being tagged or a code that no longer reflects active purchasing patterns in the market.

Recent opportunities include Seminole County, Florida's IFB for naloxone and drug deactivation systems (posted June 30, 2026, due July 26, 2023); the Texas Health and Human Services Commission's Request for Information on direct-to-manufacturer prescription programs (posted April 3, 2026); the City of Tampa's IFB for medical and first aid supplies for the Fire Department Rescue Division with an estimated contract value of $700,000.00 and SLBE set-aside (posted March 25, 2026, due March 13, 2026); and the Minnesota Multistate Cooperative Purchasing Alliance's RFP for generic multi-source pharmaceuticals and OTC products across multiple jurisdictions including Oregon (posted January 20, 2026, due March 26, 2026). None of these solicitations reference amdinocillin or mecillinam procurement. Firms pursuing this code should verify the actual commodity or service they intend to target before investing in qualification or pursuit strategy.
