UNSPSC 51283423: Oxetacillin

This classification denotes a penicillin antibiotic with the molecular formula C19H23N3O5S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 47UDJ8GA54, chemically known as (2s,5r,6r)-6-((r)-(4-(p-hydroxyphenyl)-2,2-dimethyl-5-oxo-1-imidazolidinyl)-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid but more generally known as oxetacillin, which bears US NIH Compound Identifier 6367080.

UNSPSC 51283423 Oxetacillin is a Commodity code representing pharmaceutical products procured by state and local health agencies. The recent opportunities posted under this code show little alignment with the nominal scope — the two most recent records name other pharmaceutical products (Doxycycline Hyclate, Ciprofloxacin Hydrochloride, and Naloxone) rather than Oxetacillin itself. State and local health departments and county health authorities are the issuing bodies active under this code, purchasing pharmaceutical supplies through cooperative purchasing vehicles (such as MMCAP Infuse consortiums) and competitive sealed bids to support public health initiatives and emergency response capacity.

Activity appears concentrated in the Southeast and Midwest. The Illinois Department of Public Health awarded a $2,999,999.11 contract through the MMCAP Infuse consortium piggyback to Chartwell Rx LLC on August 28, 2026 for a 12-month initial term with two renewal options, procuring two antibiotic formulations (Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg) through an Invitation for Bid. Seminole County, Florida issued an IFB (Solicitation Number IFB60459723LAS) on June 30, 2026 with a July 26, 2023 due date 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 and a two-year initial term plus one-year renewal option. Neither opportunity explicitly required set-aside utilization. The mismatch between the code's nominal pharmaceutical product and the antibiotic and emergency-response-supply focus of actual recent solicitations suggests this code may be tagged inconsistently in state and local procurement systems, warranting verification before pursuit.
