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 is a Commodity code with minimal relevant recent activity in state and local procurement. The two most recent opportunities tagged to this code show a significant mismatch with its nominal scope: Broward County Aviation Department posted an RFI on June 25, 2026 (due July 28, 2026) for maintenance services on Rapiscan X-ray inspection systems, a highly specialized equipment-service engagement unrelated to sulfobromophthalein; Pasco County, Florida 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, which addresses copper sulfate compounds but not the specific chemical code assigns. Neither opportunity reflects procurement of sulfobromophthalein itself or related diagnostic or therapeutic agents that the code nominally covers.

The geographic spread is limited to Florida (Broward and Pasco counties) in the recent window, with no visible activity from other states or issuing-body types such as state departments, school districts, or transit authorities. The code shows insufficient recent activity to establish a meaningful pattern of state and local demand. Business development professionals should verify whether sulfobromophthalein is actually purchased through state and local procurement channels or whether tagging errors account for the apparent activity under this code.
