UNSPSC 51283507: Cloxacillin sodium

This classification denotes a penicillin antibiotic with the molecular formula C19H17ClN3O5S.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 65LCB00B4Y, chemically known as 6-(((3-(2-chlorophenyl)-5-methyl-4-isoxazolyl)carbonyl)amino)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid but more generally known as cloxacillin sodium, which bears US NIH Compound Identifier 6098.

UNSPSC 51283507 Cloxacillin sodium, a Commodity code, shows limited recent state and local procurement activity directly aligned with the antibiotic pharmaceutical itself. Instead, the code's recent opportunities reflect broader pharmaceutical procurement patterns: state and local health agencies are sourcing generic pharmaceuticals, over-the-counter products, medical supplies for emergency response, and naloxone as part of community health and opioid-response initiatives. The actual buying reflects a shift toward direct-to-manufacturer relationships, cooperative purchasing arrangements, and multi-source generic drug programs rather than single-drug acquisitions. State and local issuers—including county health departments, fire and emergency services divisions, and state health commissions—are using cooperative purchasing vehicles and competitive bidding to manage pharmaceutical spend across multiple line items and therapeutic categories rather than procuring cloxacillin as a standalone commodity.

Recent opportunities span Florida, Texas, and Minnesota, with activity driven by state HHS commissions, county community health systems, municipal fire departments, and multistate cooperative purchasing alliances. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration, issued an RFP on January 20, 2026 (due March 26, 2026) for generic multi-source pharmaceuticals and OTC products through authorized wholesalers, weighted heavily on price competitiveness (75 percent) and requiring cGMP and Drug Supply Chain Security Act compliance; Seminole County, Florida solicited an IFB (due July 26, 2023) for naloxone and drug deactivation systems with quarterly deliveries; and the City of Tampa issued an IFB on March 25, 2026 (due March 13, 2026) for 169 line items of medical and first-aid supplies for the Fire Department Rescue Division, estimated at $700,000, with a 5 percent SLBE bid discount. The Texas Health and Human Services Commission posted an RFI on April 3, 2026 for Direct-to-Manufacturer Prescriptions capability as a market-intelligence phase prior to formal RFP issuance. The code shows no recent dedicated single-drug procurements for cloxacillin specifically.
