UNSPSC 51283303: Linezolid

This classification denotes an antibiotic with the molecular formula C16H20FN3O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier ISQ9I6J12J, chemically known as acetamide, n-(((5s)-3-(3-fluoro-4-(4-morpholinyl)phenyl)-2-oxo-5-oxazolidinyl)methyl)- but generally known as linezolid, which bears US NIH Compound Identifier 73180. European Medicines Agency schedules Linezolid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08520MIG.

UNSPSC 51283303 Linezolid, a Commodity code, nominally covers a specific antibiotic pharmaceutical product, but the recent state and local opportunities posted under this code show little alignment with linezolid procurement itself. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract through the MMCAP Infuse consortium to Chartwell Rx LLC in August 2026 for Doxycycline Hyclate and Ciprofloxacin Hydrochloride—different antibiotics entirely. Seminole County, Florida released a competitive bid in June 2026 for Naloxone and Safe Drug Deactivation Systems, which fall outside antibiotic scope entirely. The mismatch between the code's nominal scope and the actual work being solicited suggests the code sees limited relevant recent activity for linezolid-specific procurement, or that tagging practices at these issuing bodies do not cleanly separate pharmaceutical products by active ingredient.

The issuing bodies using this code include state health departments and county health authorities. The Illinois Department of Public Health's August 2026 award to Chartwell Rx LLC totaled $2,999,999.11 over 12 months with two renewal options; the contract required an Invitation for Bid process with lowest-priced responsive and responsible selection. Seminole County's June 2026 IFB (IFB60459723LAS) sought annual delivery of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems on a two-year initial term with one-year renewal option, with quarterly deliveries to the Seminole County Community Health Building and potential FEMA funding. Activity appears concentrated in Florida and Illinois; no recent linezolid-specific solicitations are evident in the source material.
