UNSPSC 51442603: Sulfobromophthalein sodium

This classification denotes a dye with the molecular formula C20H8Br4O10S2.2Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 62E5JU30OV, chemically known as 4,5,6,7-tetrabromo-3,3-disulfophenolphthalein disodium salt but more generally known as sulfobromophthalein sodium, which bears U.S. National Institutes of Health Compound Identifier 6282.

UNSPSC 51442603 Sulfobromophthalein sodium is a Commodity code that shows little relevant recent activity aligned with its nominal scope. The two most recent state and local opportunities tagged under this code are fundamentally unrelated to sulfobromophthalein sodium: Broward County Aviation Department's June 2026 RFI concerns maintenance services for Rapiscan X-ray inspection systems, and Pasco County, Florida's June 2026 RFQ solicits copper sulfate crystals and liquid copper sulfate for as-needed supply. Neither opportunity involves the diagnostic or pharmaceutical agent the code nominally describes. The mismatch suggests either inconsistent coding practice in these jurisdictions' procurement systems or that this code is rarely used for its intended commodity classification in state and local contracting.

No representative opportunities under UNSPSC 51442603 for sulfobromophthalein sodium itself are present in the source. Vendors tracking this code for state and local procurement activity should monitor whether the coding classification stabilizes or whether future solicitations more accurately reflect the intended commodity scope.
