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 under which state and local governments are procuring radiologic and X-ray equipment, installation services, and associated maintenance and warranty coverage for medical and security imaging systems. The recent solicitations show purchasing activity centered on replacement equipment, extended service plans, and specialized repair capability for diagnostic and inspection X-ray systems across healthcare and correctional facilities. The issuing bodies soliciting under this code include county governments (Maricopa County, Escambia County, Broward County, and Pasco County in Florida and Arizona) and county-level departments including corrections and aviation authorities. The scope extends beyond the nominal chemical commodity to encompass equipment procurement, installation, warranty administration, and specialized maintenance services for complex X-ray imaging systems — a significant mismatch between the code's apparent pharmaceutical focus and the actual state and local buying activity.

Recent opportunities include Maricopa County's IFB 362910 for radiologic equipment and installation services at three college locations (due October 22, 2026); Escambia County Correction's sole-source procurement (SSCORALM2526005) for an extended warranty on X-Ray machines (due August 19, 2026); Broward County Aviation Department's RFI (BLD2132311F1) issued June 25, 2026, testing the market for maintenance services on Rapiscan X-ray inspection systems and seeking vendors capable of competing with or challenging the sole-source designation; and Pasco County's RFQ (RFQFP261004) for on-an-as-needed supply of large copper sulfate crystals and liquid copper sulfate (due June 26, 2026). Activity concentrates in Florida (Escambia, Broward, and Pasco counties) and Arizona (Maricopa County). The code shows little relevant recent activity aligned with its stated pharmaceutical scope; the radiologic equipment and X-ray service opportunities appear misclassified.
