UNSPSC 51282315: Erythromycin enol ether

This classification denotes a macrolide antibiotic with the molecular formula C37H65NO12, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 32B40I7V7B, chemically known as erythromycin, 8,9-didehydro-9-deoxo-6-deoxy-6,9-epoxy-, but more generally known as erythromycin enol ether, which bears US NIH Compound Identifier 6426642. European Medicines Agency schedules erythromycin enol ether or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06605MIG.

Most nations, for tariff purposes, schedule erythromycin enol ether under HS 29415000. SMILES: CC[C@@H]1[C@@]([C@@H]([C@H](C2=C(C[C@@](O2)([C@@H]([C@H]([C@@H]([C@H](C(=O)O1)C)O[C@H]3C[C@@]([C@H]([C@@H](O3)C)O)(C)OC)C)O[C@H]4[C@@H]([C@H](C[C@H](O4)C)N(C)C)O)C)C)C)O)(C)O.

UNSPSC 51282315 Erythromycin enol ether is a Commodity code that maps poorly to recent state and local procurement activity. The code nominally describes a specific pharmaceutical compound, but the four recent opportunities posted under it involve naloxone distribution systems, direct-to-manufacturer pharmacy initiatives, emergency medical and first-aid supplies, and multi-source generic pharmaceuticals and OTC products — none of which are erythromycin enol ether or direct substitutes. The mismatch suggests either tagging error in the sourcing systems or a broadened application of the code to capture general pharmaceutical procurement. State and local issuers applying this code include county health departments (Seminole County, Florida), state health and human services agencies (Texas HHS Commission), municipal fire departments (City of Tampa), and cooperative purchasing organizations (Minnesota Multistate Cooperative Purchasing Alliance).

Activity spans Florida, Texas, Minnesota, and Oregon. Representative recent opportunities include Seminole County's IFB 60459723LAS (posted June 30, 2026, response due July 26, 2023) for 1,900 units of naloxone and 800 drug deactivation systems annually to the county health building; the City of Tampa's invitation to bid 26P00145 (due March 13, 2026) for 169 line items of medical and emergency response supplies for the Fire Department Rescue Division, with an estimated contract value of $700,000 and a sheltered-market set-aside for certified Small Local Business Enterprises; and the Minnesota Multistate Cooperative Purchasing Alliance RFP S1070000015802 (due March 26, 2026) for generic multi-source pharmaceuticals and OTC products distributed across state and local government facilities. The Texas HHS Commission RFI HHS0017013 (due April 3, 2026) represents exploratory procurement rather than a formal competitive solicitation. Given the code's nominal scope and the absence of erythromycin-specific procurement in the recent block, activity under this code does not support targeted business development for pharmaceutical manufacturers or suppliers specializing in that compound.
