UNSPSC 51283214: Josamycin propionate

This classification denotes a macrolide antibiotic with the molecular formula C45H73NO16, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 053VA4B06Y, chemically known as leucomycin v, 3-acetate 4b-(3-methylbutanoate) 9-propanoate but more generally known as josamycin propionate, which bears US NIH Compound Identifier 5353696. European Medicines Agency schedules Josamycin propionate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB02814MIG.

UNSPSC 51283214 Josamycin propionate is a Commodity code that does not align with recent state and local procurement activity. The code nominally describes a macrolide antibiotic pharmaceutical, but the recent opportunities posted under this code span naloxone procurement, therapeutic pharmacy initiatives, emergency medical supplies, and generic pharmaceuticals—none of which feature josamycin propionate as a product line. State and local health agencies, county governments, and cooperative purchasing alliances are actively soliciting these related products and services, but the specific antibiotic named in the code title does not appear in any of the recent solicitations reviewed.

The mismatch between the code definition and actual buying patterns suggests either a cataloging error in how opportunities were tagged or that josamycin propionate sees minimal demand in state and local procurement. The broader pharmaceutical and medical supply landscape remains active—the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) is managing a two-year RFP for generic pharmaceuticals and OTC products with responses due March 26, 2026; Seminole County, Florida is procuring naloxone and drug deactivation systems through an IFB posted June 30, 2026; and the City of Tampa is seeking emergency medical supplies for its Fire Department Rescue Division under a sheltered SLBE procurement with a $700,000 estimated value. However, none of these opportunities reference josamycin propionate directly. Firms pursuing pharmaceutical-related state and local contracts should verify code assignment in RFP packages before responding, as this commodity code shows little relevant recent activity.
