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 is a Commodity code representing pharmaceutical products procured through state and local health agencies, but recent state and local contract activity under this code shows little direct relevance to erythromycin itself. The Illinois Department of Public Health and Seminole County, Florida—both significant health procurement bodies—have posted opportunities tagged to this code, yet the actual goods being solicited diverge substantially from the nominal commodity. The Illinois opportunity, awarded to Chartwell Rx LLC in August 2026, supplies Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets through a piggyback contract via the MMCAP Infuse consortium, representing pharmaceutical warehouse supply under a 12-month initial term with renewal options and a total contract value of $2,999,999.11 across all periods. The Seminole County, Florida procurement targets Naloxone and Safe Drug Deactivation Systems for community health initiatives, requiring 1,900 units of Naloxone and 800 deactivation systems annually with quarterly deliveries to the county's Community Health Building in Sanford.

State health departments and county health agencies are the issuing bodies visible under this code in recent activity. Geographically, recent opportunities cluster in Illinois and Florida. The Illinois Department of Public Health awarded its pharmaceutical piggyback contract through a competitive IFB process to a single vendor as the lowest priced responsive and responsible bidder, with no set-aside designations or domestic product preferences applied. The Seminole County opportunity, posted June 30, 2026 with a July 26, 2023 response deadline, was competitively bid through the county's e-Procurement Portal and requires vendors to meet drug-free workplace certification, E-Verify compliance, and standard insurance requirements; the contract includes a three-month probationary termination clause and potential FEMA funding, which triggers federal compliance obligations including the Clean Air Act and Federal Water Pollution Control Act. The mismatch between the code's nominal scope and the pharmaceuticals actually being procured—antibiotics and opioid reversal agents rather than erythromycin specifically—suggests either miscoding at the source or that the code functions as a catch-all for state and local pharmaceutical purchases across multiple active ingredient families.
