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 is a Commodity code for a specific antibiotic pharmaceutical product, but state and local procurement activity under this code shows little relevant recent posting. The most recent opportunities tagged to this code actually solicit different medications — Doxycycline Hyclate, Ciprofloxacin Hydrochloride, and Naloxone — rather than cloxacillin sodium itself. State and local health departments and county public health agencies are the primary issuing bodies when they do acquire antibiotics and emergency medical supplies through competitive processes, typically via piggyback arrangements on established pharmaceutical consortiums or direct procurement through invitation for bid. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract to Chartwell Rx LLC for $2,999,999.11 over three years for antibiotic tablets through the MMCAP Infuse consortium, while Seminole County, Florida sought Naloxone and drug deactivation systems for annual delivery to county health facilities.

The geographic footprint of recent activity is limited to Illinois and Florida, with no evidence of widespread state-level or multi-jurisdictional solicitations for cloxacillin sodium specifically. Buyers appear concentrated among state health departments and county health authorities pursuing supplies through established cooperative purchasing vehicles or competitive sealed bids. The Illinois Department of Public Health contract (awarded August 28, 2026 under IFB process) and the Seminole County procurement (IFB60459723LAS, due July 26, 2026) represent the only recent opportunities in the block, both involving pharmaceutical or emergency medical supplies but neither explicitly naming cloxacillin sodium as a line item. Business development activity under this code should be evaluated on whether your firm is actively pursuing pharmaceutical supply contracts with state health departments or county public health systems; the mismatch between the code's nominal scope and actual recent opportunities suggests limited or inaccurate tagging at the source level.
