UNSPSC 51282408: Mezlocillin sodium

This classification denotes an extended spectrum penicillin antibiotic with the molecular formula C21H24N5O8S2.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier RX227TP94U, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 3,3-dimethyl-6-(((((((3-(methylsulfonyl)-2-oxo-1-imidazolidinyl)carbonyl)amino)carbonyl)amino)phenylacetyl)amino)-7-oxo-, monosodium salt, (2s-(2alpha,5alpha,6beta(s*)))- but generally known as mezlocillin sodium, which bears US NIH Compound Identifier 43084.

UNSPSC 51282408 Mezlocillin sodium is a Commodity code that, based on recent state and local solicitations, does not align with actual procurement activity under this designation. The code nominally identifies a specific antibiotic pharmaceutical, but the recent opportunities posted under it involve naloxone kits, first aid and rescue supplies, generic multi-source pharmaceuticals, and prescription drug programs — none of which are mezlocillin sodium. The mismatch suggests either miscoding by issuing bodies or a data artifact in how opportunities were tagged; the code shows little relevant recent activity for its stated product.

The source includes four recent opportunities across three jurisdictions: Seminole County, Florida (IFB for naloxone and drug deactivation systems, due July 26, 2023); the City of Tampa, Florida (IFB for medical and first aid supplies for the Fire Department Rescue Division, due March 13, 2026, with a $700,000 estimated contract value and a 5 percent bid discount for certified Small Local Business Enterprises); the Minnesota Multistate Cooperative Purchasing Alliance administered by the Minnesota Department of Administration (RFP for generic multi-source pharmaceuticals and OTC products, due March 26, 2026); and the Texas Health and Human Services Commission (RFI for direct-to-manufacturer prescription programs, posted April 3, 2026). The opportunities span Florida, Minnesota, Texas, and Oregon (through MMCAP), with issuing bodies ranging from county health departments and city fire departments to state cooperative purchasing vehicles. None of the work described matches the mezlocillin sodium commodity code; firms pursuing this code should verify the correct UNSPSC classification with target agencies before bidding.
