UNSPSC 51441901: Acetrizoic acid

This classification denotes a contrast agent with the molecular formula C9H6I3NO3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 24256BQV7M, chemically known as 3-(acetylamino)-2,4,6-triiodobenzoic acid but more generally known as acetrizoic acid, which bears U.S. National Institutes of Health Compound Identifier 6806. The European Medicines Agency schedules Acetrizoic acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB00256MIG.

The World Health Organization schedules acetrizoic acid in its Anatomical Therapeutic Chemical (ATC) Classification. Most nations schedule Acetrizoic acid under HS 29242995. SMILES: IC1C(NC(=O)C)C(I)CC(I)C1C(=O)O.

UNSPSC 51441901 Acetrizoic acid is a Commodity code that describes state and local procurement of diagnostic imaging chemicals and related radiologic supplies, though recent solicitations show the code is being applied to a broader range of X-ray equipment maintenance, installation, and chemical supply needs. The issuing bodies purchasing under this code span county health systems, county corrections departments, county aviation authorities, and county water utilities. Maricopa County Community Colleges, Escambia County Correction, Broward County Aviation Department, and Pasco County have posted opportunities in the past four months, reflecting a mix of institutional and operational buyers. The actual work being solicited includes radiologic equipment procurement and installation at educational facilities, extended warranty and specialized maintenance services for X-ray systems used in corrections and aviation security screening, and bulk chemical supplies for water treatment operations.

Recent activity concentrates in Florida and Arizona. Maricopa County posted IFB 362910 on October 1, 2026, for radiologic equipment and installation services at three colleges with responses due October 22, 2026. Escambia County Correction issued a sole-source IFB (SSCORALM2526005) on August 12, 2026, for an extended warranty on X-ray machines with an August 19 closing. Broward County Aviation Department issued an RFI (BLD2132311F1) on June 25, 2026, to explore whether maintenance services for Rapiscan X-ray inspection systems used in security screening are available from vendors other than the sole manufacturer, with responses due July 28, 2026. Pasco County posted an RFQ on June 3, 2026, for as-needed supply of large copper sulfate crystals and liquid copper sulfate, closing June 26, 2026. The code shows active procurement interest across medical equipment, security systems, and water-treatment chemical supply, though the tagged opportunities suggest inconsistent application of the acetrizoic acid code to work that spans multiple commodity families.
