UNSPSC 51442421: Iohexol

This classification denotes an iodinated contrast dye with the molecular formula C19H26I3N3O9, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4419T9MX03, chemically known as 1,3-benzenedicarboxamide, 5-(acetyl(2,3-dihydroxypropyl)amino)-n,n-bis(2,3-dihydroxypropyl)-2,4,6-triiodo but more generally known as iohexol, which bears U.S. National Institutes of Health Compound Identifier 3730. The European Medicines Agency schedules Iohexol in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08228MIG.

UNSPSC 51442421 Iohexol is a Commodity code, but recent state and local opportunities posted under it show no solicitations for iohexol itself or other pharmaceutical contrast agents. Instead, the two most recent opportunities tagged to this code concern X-ray system maintenance services and copper sulfate chemicals—products unrelated to the code's nominal scope. The mismatch signals that this code sees little relevant recent activity in state and local procurement, and opportunities appearing under it do not reflect the intended commodity classification.

Activity under this code is sparse and geographically scattered. The two recent opportunities originate from Florida jurisdictions: Broward County Aviation Department issued an RFI on June 25, 2026 (due July 28, 2026) exploring maintenance-service providers for proprietary Rapiscan X-ray inspection systems, and Pasco County posted an RFQ on June 3, 2026 (due June 26, 2026) for large copper sulfate crystals and liquid copper sulfate on an as-needed basis. Neither solicitation aligns with pharmaceutical contrast media procurement. State and local procurement offices do not appear to be using this code actively for iohexol or related products in the current market window.
