UNSPSC 51442440: Sodium tyropanoate or tyropanoic acid

This classification denotes a contrast media with the molecular formula C15H18I3NO3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4F05V145YR, chemically known as 3-butyramido-alpha-ethyl-2,4,6-triiodohydrocinnamic acid sodium salt but more generally known as tyropanoic acid, which bears U.S. National Institutes of Health Compound Identifier 23676. The European Medicines Agency schedules Tyropanoic acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05028MIG.

The World Health Organization schedules tyropanoic acid in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: CCCC(=O)NC1=C(C=C(C(=C1I)CC(CC)C(=O)[O-])I)I.[Na+]. Most nations schedule Sodium tyropanoate or tyropanoic acid under HS 29242995.

UNSPSC 51442440 Sodium tyropanoate or tyropanoic acid is a Commodity code that nominally identifies diagnostic pharmaceutical contrast agents, yet recent state and local solicitations tagged under this code show minimal alignment with that scope. The opportunities posted include radiologic equipment procurement, X-ray system maintenance and warranty services, and chemical supplies (copper sulfate), none of which are sodium tyropanoate or related contrast media. The mismatch suggests either miscoding in the issuing bodies' systems or that this code has become a catch-all for miscellaneous medical and scientific procurement when proper classifications are unavailable.

The recent activity spans three states — Arizona, Florida (two jurisdictions), and does not support a pattern of repeat buyers or sustained geographic concentration. Maricopa County issued an IFB for radiologic equipment and installation at three colleges (due October 22, 2026); Escambia County Correction solicited an extended warranty for X-ray machines under sole-source procurement (due August 19, 2026); Broward County Aviation Department posted an RFI to determine whether maintenance services for Rapiscan X-ray inspection systems are available from multiple vendors or remain sole-source (responses due July 28, 2026); and Pasco County issued an RFQ for copper sulfate crystals and liquid on an as-needed basis (due June 26, 2026). The code shows little relevant recent activity and lacks coherence around the nominal commodity, limiting utility for vendors specializing in contrast agents or pharmaceutical diagnostics.
