UNSPSC 51441907: Metrizoic acid

This classification denotes a contrast agent with the molecular formula C12H11I3N2O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier CM1N99QR1M, chemically known as 3-(acetylamino)-5-(acetyl(methyl)amino)-2,4,6-triiodobenzoic acid but more generally known as metrizoic acid, which bears U.S. National Institutes of Health Compound Identifier 2528. The European Medicines Agency schedules Metrizoic acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03276MIG.

The World Health Organization schedules metrizoic acid in its Anatomical Therapeutic Chemical (ATC) Classification. Most nations schedule Metrizoic acid under HS 29242995. SMILES: CC(=O)NC1C(C(C(C(C1I)N(C)C(=O)C)I)C(=O)O)I.

UNSPSC 51441907 Metrizoic acid is a Commodity code that shows minimal alignment with recent state and local procurement activity. The two most recent opportunities posted under this code involve X-ray system maintenance services (Broward County Aviation Department) and copper sulfate supply (Pasco County, Florida)—neither of which relates to metrizoic acid, a contrast medium used in medical imaging. The code appears to be applied inconsistently or inaccurately by issuing bodies, suggesting either data-entry error or misalignment between the UNSPSC taxonomy and how jurisdictions are tagging their solicitations. State and local procurement under this specific code shows no discernible pattern of actual metrizoic acid purchasing based on the available opportunities.

The geographic activity identified spans Florida counties only, with Broward County and Pasco County each appearing once in recent postings. Broward County Aviation Department issued an RFI (Request for Information) on June 25, 2026, due July 28, 2026, to determine whether maintenance services for Rapiscan X-ray inspection systems are available from sources other than the original vendor; this was a sole-source determination notice, not a commodity procurement. Pasco County posted an RFQ (Request for Quotation) on June 3, 2026, due June 26, 2026, for as-needed supply of large copper sulfate crystals and liquid copper sulfate under an indefinite-quantity arrangement. Neither opportunity reflects the nominal scope of metrizoic acid procurement. The code warrants close monitoring to distinguish whether future activity will align with its intended scope or continue to reflect miscoding by state and local jurisdictions.
