UNSPSC 51442604: Sulfobromophthalein

This classification denotes a dye with the molecular formula C20H10Br4O10S2, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier 0C2P5QKL36, chemically known as 3,3-(4,5,6,7-tetrabromo-3-oxo-1(3h)-isobenzofuranylidene)bis(6-hydroxybenzenesulphonic) acid but more generally known as sulfobromophthalein, which bears U.S. NIH Compound Identifier 5345. World Health Organization schedules sulfobromophthalein in its Anatomical Therapeutic Chemical (ATC) Classification and its WHO-DD or Drug Dictionary.

UNSPSC 51442604 Sulfobromophthalein, a Commodity code, does not align with the state and local procurement activity currently tagged under it. The recent opportunities posted against this code span radiologic and X-ray equipment procurement, extended warranties for diagnostic imaging systems, maintenance services for specialized inspection equipment, and chemical supplies—none of which are pharmaceutical agents or diagnostic dyes related to the code's nominal scope. The mismatch suggests either metadata errors in the tagging systems of the issuing bodies or use of the code as a catch-all for diagnostic and technical equipment categories where more precise coding is unavailable. State and local procurement offices across multiple jurisdictions (Maricopa County, Arizona; Escambia County, Florida; Broward County, Florida; and Pasco County, Florida) have recently posted solicitations carrying this code, but their actual buying activity does not reflect the substance of sulfobromophthalein procurement.

The three most recent tagged opportunities include Maricopa County's IFB 362910 for radiologic equipment and installation at three colleges with responses due October 22, 2026; Escambia County Correction's sole-source procurement (SSCORALM2526005) for extended warranty coverage on X-ray machines with responses due August 19, 2026; and Broward County Aviation Department's RFI issued June 25, 2026 seeking competing sources or alternate systems for Rapiscan X-ray inspection equipment maintenance. A fourth opportunity from Pasco County (RFQFP261004), posted June 3, 2026 with a due date of June 26, 2026, solicited copper sulfate crystals and liquid copper sulfate on an as-needed basis. The geographic concentration in Florida (three of four recent opportunities) reflects current activity, though the code itself shows little meaningful signal for business development targeting authentic sulfobromophthalein or related pharmaceutical procurement.
