UNSPSC 51441902: Amidotrizoic acid or diatrizoate or diatrizoic acid

This classification denotes a contrast agent that practitioners often use (along with this commodity's ester) in x-ray and/or computed tomography (ct) liver studies, an agent with the molecular formula C11H9I3N2O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 5UVC90J1LK, chemically known as 2,4,6-triiodo-3,5-diacetamidobenzoic acid but more generally known as diatrizoate, which bears U.S. National Institutes of Health Compound Identifier 2140. Most nations schedule Amidotrizoic acid or diatrizoate or diatrizoic acid under HS 29242995.

SMILES: CC(=O)NC1C(C(C(C(C1I)NC(=O)C)I)C(=O)[O-])I.[NA+].

UNSPSC 51441902 Amidotrizoic acid or diatrizoate or diatrizoic acid (Commodity) covers contrast media and related radiologic supplies, but recent state and local solicitations tagged to this code show limited alignment with the nominal scope. The most recent opportunities posted under this code span X-ray equipment procurement, extended warranty services for imaging systems, maintenance service plans for proprietary inspection equipment, and chemical supplies — none of which directly correspond to amidotrizoic acid or diatrizoate contrast agents. The mismatch suggests either code misapplication in the source system or that this Commodity code is being used as a catch-all for radiologic and imaging-related purchases that fall outside narrower classifications.

Activity appears concentrated in Florida counties and Arizona, with Maricopa County (Arizona), Escambia County Correction (Florida), Broward County Aviation Department (Florida), and Pasco County (Florida) posting opportunities between June and October 2026. Maricopa County issued an IFB (IFB362910) for radiologic equipment and installation services at three colleges due October 22, 2026; Escambia County Correction issued a sole-source IFB (SSCORALM2526005) for extended warranty coverage on specified X-ray machines due August 19, 2026; and Broward County Aviation Department posted an RFI (BLD2132311F1) June 25, 2026 (due July 28) challenging a sole-source designation for Rapiscan X-ray system maintenance services. The code shows no recent opportunities directly soliciting contrast media compounds.
