UNSPSC 51283419: Phenoxymethylpenicillin calcium

This classification denotes a penicillin antibiotic 2C16H17N2O5S.Ca, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 3750YH4NM7, chemically known as 4-thia-1-azabicyclo(3.2.0)heptane-2-carboxylic acid, 3,3-dimethyl-7-oxo-6-((phenoxyacetyl)amino)-, calcium salt (2:1), (2s,5r,6r)-, but more generally known as phenoxymethylpenicillin calcium, which bears US NIH Compound Identifier 46174101.

UNSPSC 51283419 Phenoxymethylpenicillin calcium is a Commodity code that shows substantial mismatch between its nominal scope and recent state and local solicitation activity. The code nominally covers a specific penicillin-class antibiotic formulation, yet the recent opportunities posted under this code involve naloxone and drug deactivation systems, direct-to-manufacturer prescription programs, broad medical and first aid supplies, and multi-source generic pharmaceuticals and OTC products—none of which align with phenoxymethylpenicillin calcium procurement. The state and local buyers posting under this code span health departments, state pharmacy benefit administrators, and municipal fire departments, with no clear pattern of consistent use or repeat buyers evident in the recent activity.

Geographic activity appears concentrated in Florida (Seminole County), Texas (HHS Commission), and Minnesota (MMCAP cooperative), with one opportunity spanning multiple states through the Minnesota multistate purchasing vehicle. Representative recent opportunities include Seminole County's IFB 60459723LAS for naloxone and drug deactivation systems (due July 26, 2023, though the posting date is June 30, 2026—indicating a date anomaly in the source); the City of Tampa's IFB 26P00145 for medical and first aid supplies for the Fire Department Rescue Division, estimated at $700,000.00 with response due March 13, 2026 and a 5 percent SLBE bid discount; and MMCAP's RFP S1070000015802 for generic pharmaceuticals and OTC products, due March 26, 2026, distributed through authorized wholesalers across multiple states. The code's shallow recent-opportunity depth and category misalignment suggest either systematic tagging error across these solicitations or marginal practical relevance for vendors focused on phenoxymethylpenicillin calcium specifically. Pursue only after confirming actual buyer intent through direct contact with issuing bodies.
