UNSPSC 51282518: Cefmepidium

This classification denotes a cephalosporin antibiotic with the molecular formula C23H25N6O8S3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier XLC35939WJ, chemically known as 4-((((6r,7r)-7-(2-(2-amino-4-thiazolyl)glyoxylamido)-2-carboxy-8-oxo-5-thia-1-azabicyclo(4.2.0)oct-2-en-3-yl)methyl)thio)-1-methylpyridinium 72-(z)-(o-(1-carboxy-1-methylethyl)oxime) s-oxide. but generally known as cefmepidium, which bears US NIH Compound Identifier 9589472.

UNSPSC 51282518 Cefmepidium is a Commodity code that does not map to the recent state and local opportunities tagged under it. The code nominally refers to a specific antibiotic pharmaceutical, yet the two recent opportunities in the block describe procurement of entirely different drugs — Doxycycline Hyclate and Ciprofloxacin Hydrochloride in one instance, and Naloxone with drug deactivation systems in another. Neither opportunity involves Cefmepidium itself. The tagging mismatch suggests either a cataloging error in the source data or inconsistent code assignment by the issuing bodies. As a result, this code shows little relevant recent activity for vendors seeking to bid on Cefmepidium specifically.

The two opportunities that do appear under this code involve pharmaceutical procurement by state health departments and county health systems. The Illinois Department of Public Health awarded a three-year piggyback contract through the MMCAP Infuse cooperative purchasing vehicle to Chartwell Rx LLC on August 28, 2026, for antibiotic tablet supply totaling $2.99 million over the full contract term, while Seminole County, Florida posted an IFB on June 30, 2026, for annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with a July 26, 2023 response deadline. The issuing bodies are state-level public health agencies and county health departments; the geographic spread is limited to Illinois and Florida in the recent record. Vendors pursuing pharmaceutical supply contracts should monitor cooperative purchasing consortia and county health procurement channels, but should verify that future solicitations are correctly tagged under the commodity code matching the actual drug being procured.
