UNSPSC 51152037: Mephenoxalone

This classification denotes a muscle relaxant with the molecular formula C11H13NO4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier CZ87T54W8W, chemically known as 2-oxazolidinone, 5-((o-methoxyphenoxy)methyl)- but generally known as mephenoxalone, which bears US NIH Compound Identifier 6257. European Medicines Agency schedules Mephenoxalone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08747MIG.

UNSPSC 51152037 Mephenoxalone is a Commodity code designated for pharmaceutical products, though recent state and local solicitations tagged under this code show misalignment with the nominal scope. The two recent opportunities on file involve naloxone procurement and pharmacy benefit management services—both distinct from mephenoxalone itself. State and local governments are using this code tag to solicit pharmaceutical-adjacent services and harm-reduction products through competitive bidding processes, though the actual commodities being purchased do not match the specific chemical name assigned to the code. Issuing bodies include county health departments and state health and human services agencies conducting both traditional IFB procurements and exploratory RFI market-research activities.

Seminole County, Florida posted IFB 60459723LAS on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building, with responses due July 26, 2023. The Texas Health and Human Services Commission issued RFI HHS0017013 on April 3, 2026, to gather vendor capabilities for a direct-to-manufacturer prescription program outside traditional pharmacy benefit manager and group purchasing organization channels. The code shows sparse recent activity and exhibits a mismatch between its nominal scope (mephenoxalone, a specific pharmaceutical) and the actual procurement work being tagged under it. Prospective vendors should note that the code's application in current state and local procurement does not reflect its official UNSPSC definition, and activity remains limited to two jurisdictions with distinct procurement objectives.
