This classification denotes an extended spectrum penicillin antibiotic C21H24N5O8S2.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3CWW8B5904, chemically known as sodium (2s,5r,6r)-3,3-dimethyl-6-((r)-2-(3-(methylsulfonyl)-2-oxo-1-imidazolidinecarboxamido)-2-phenylacetamido)-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylate, monohydrate, but more generally known as mezlocillin sodium monohydrate, which bears US NIH Compound Identifier 23677831.

UNSPSC 51282420 Mezlocillin sodium monohydrate is a Commodity code for a specific injectable antibiotic pharmaceutical product; state and local governments procure it primarily through piggyback cooperative purchasing vehicles tied to master agreements negotiated at the state or regional level. Recent activity shows minimal direct solicitation under this code's specific drug identifier—the opportunities tagged to it involve broader pharmaceutical warehouse orders and naloxone procurement that do not align with mezlocillin sodium monohydrate as the primary product being sought. State and local health departments and county public health agencies are the primary buyers when antibiotic pharmaceuticals are procured, typically bundling specific drug products into larger warehouse supply agreements with quarterly or annual delivery cycles and standardized pricing structures.

Geographic activity is concentrated in Florida and Illinois based on recent records, though the opportunities posted do not represent active solicitations for mezlocillin sodium monohydrate itself. The Illinois Department of Public Health awarded a piggyback pharmaceutical contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026, for doxycycline and ciprofloxacin products totaling $2,999,999.11 over three years under an IFB process, and Seminole County, Florida posted an IFB (IFB60459723LAS) on June 30, 2026, for naloxone and drug deactivation systems with quarterly deliveries. Neither opportunity actively solicits mezlocillin sodium monohydrate; the code shows little relevant recent state and local procurement activity under its specific drug scope.
