This classification denotes a penicillin antibiotic with the molecular formula C19H18N3O5S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4TWD2995UP, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 3,3-dimethyl-6-(((5-methyl-3-phenyl-4-isoxazolyl)carbonyl)amino)-7-oxo-, sodium salt (1:1), (2s,5r,6r)-, but more generally known as oxacillin sodium anhydrous, which bears US NIH Compound Identifier 64714.

UNSPSC 51283517 Oxacillin sodium anhydrous is a Commodity code for a specific antibiotic pharmaceutical product, but the recent state and local opportunities tagged under it do not reflect procurement of oxacillin itself. Instead, the opportunities on record involve related pharmaceutical products — primarily Doxycycline Hyclate, Ciprofloxacin Hydrochloride, and Naloxone — procured through piggyback contracts and competitive bidding. State and local health departments and county public health agencies use this code tier to source antibiotics and emergency medical pharmaceuticals through centralized procurement vehicles such as cooperative purchasing consortiums and traditional Invitation for Bid processes. The scope of work centers on bulk pharmaceutical supply with defined package sizes, expiration periods, and tiered renewal options over multi-year contract terms.

The Illinois Department of Public Health awarded a piggyback pharmaceutical contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for $2,999,999.11 over 12 months plus two optional renewal years, supplying Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets. Seminole County, Florida released an IFB in June 2026 (response deadline July 26, 2023) for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. Geographic activity centers on Florida and Illinois, though the dataset does not support a broader regional characterization. Cooperative purchasing vehicles and traditional competitive bidding both appear as procurement methods for pharmaceutical supply at the state health department and county level.
