UNSPSC 51282324: Erythromycin phosphate

This classification denotes a macrolide antibiotic with the molecular formula C37H67NO13.H3O4P, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier I8T8KU14X7, chemically known as erythromycin, phosphate but more generally known as erythromycin phosphate, which bears US NIH Compound Identifier 83935. Most nations, for tariff and trade purposes, schedule erythromycin phosphate under HS 29415000 and SITC 54139. As of Q4 2014, ERYTHROMYCIN PHOSPHATE remains US FDA's Preferred Term for this commodity.

Erythromycin phosphate bears US NLM identifiers UMLS ID C0014813 and NCI Concept Code C87759. SMILES: CC[C@@H]1[C@@]([C@@H]([C@H](C(=O)[C@@H](C[C@@]([C@@H]([C@H]([C@@H]([C@H](C(=O)O1)C)O[C@H]2C[C@@]([C@H]([C@@H](O2)C)O)(C)OC)C)O[C@H]3[C@@H]([C@H](C[C@H](O3)C)N(C)C)O)(C)O)C)C)O)(C)O.OP(=O)(O)O.

UNSPSC 51282324 Erythromycin phosphate, a Commodity code, shows limited alignment between its nominal scope and actual state and local procurement activity. Recent opportunities tagged to this code involve naloxone kits, medical first-aid supplies for fire rescue, and generic multi-source pharmaceuticals and OTC products—none of which are erythromycin-specific or directly match the antibiotic's therapeutic class. The issuing bodies span county health departments (Seminole County, Florida), municipal fire operations (City of Tampa), state health commissions (Texas Health and Human Services Commission), and multistate cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance). The purchases reflect institutional healthcare procurement—routine supply of emergency response and pharmacy benefit items rather than targeted pharmaceutical procurement under a single active ingredient.

Recent activity appears concentrated in Florida and the upper Midwest, with Texas engagement through preliminary information-gathering via RFI rather than active competitive bidding. Representative opportunities include Seminole County's IFB for naloxone and drug deactivation systems (IFB60459723LAS, due July 26, 2023), the City of Tampa's sealed-bid solicitation for medical and first aid supplies including respiratory and cardiac monitoring equipment (26P00145, due March 13, 2026, estimated $700,000 with SLBE set-asides), the Minnesota Multistate Cooperative Purchasing Alliance's RFP for generic multi-source pharmaceuticals and OTC products (S1070000015802, due March 26, 2026), and Texas HHS's exploratory RFI on direct-to-manufacturer prescription programs (HHS0017013, posted April 3, 2026). The code does not currently reflect active procurement of erythromycin phosphate specifically; vendors seeking work under this code should verify the actual pharmaceutical and therapeutic focus of individual opportunities before pursuing.
