UNSPSC 51283512: Meticillin sodium

This classification denotes a penicillin antibiotic with the molecular formula C17H19N2O6S.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier AO9YF4MN30, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 6-((2,6-dimethoxybenzoyl)amino)-3,3-dimethyl-7-oxo-, monosodium salt, monohydrate, (2s-(2alpha,5alpha,6beta))- but more generally known as methicillin sodium, which bears US NIH Compound Identifier 23675.

European Medicines Agency schedules Meticillin sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03264MIG. Most nations, for tariff and trade purposes, schedule meticillin sodium under HS 29411090. SMILES: CC1([C@@H](N2[C@H](S1)[C@@H](C2=O)NC(=O)C3C(CCCC3OC)OC)C(=O)[O-])C.[NA+].

UNSPSC 51283512 Meticillin sodium is a Commodity code that nominally describes antibiotic pharmaceuticals, but the recent state and local opportunities posted under this code show little direct alignment with meticillin procurement. The Illinois Department of Public Health awarded a $2,999,999.11 piggyback pharmaceutical warehouse contract to Chartwell Rx LLC through the MMCAP Infuse consortium on August 28, 2026, for Doxycycline Hyclate 100mg and Ciprofloxacin Hydrochloride 500mg tablets—neither meticillin products. Seminole County, Florida posted an IFB on June 30, 2026, for procurement of naloxone and drug deactivation systems, also outside the meticillin scope. State and local purchasing offices appear to use this code as a broader catch-all for pharmaceutical acquisitions rather than as a meticillin-specific line item, and the issuing bodies include state health departments and county community health programs sourcing critical-care and emergency-response pharmaceuticals through cooperative purchasing vehicles and competitive bidding.

Activity under the code concentrates in Florida and Illinois based on the recent postings, though the sparse record limits geographic characterization. The Illinois contract represents a completed award through a consortium piggyback arrangement with a 12-month initial term and two renewal options, while the Seminole County IFB (posted June 30, 2026, with response deadline July 26, 2026) structured annual procurement with quarterly deliveries and a two-year initial term plus one-year renewal option. Both solicitations emphasize delivery logistics, compliance certifications (drug-free workplace, E-Verify), and insurance requirements. The fundamental signal is one of misalignment: vendors pursuing meticillin-specific sales to state and local health systems should verify that purchasing offices are actually tagging meticillin-denominated contracts under this code rather than treating it as a generic pharmaceutical acquisition classification.
