UNSPSC 51442436: Rose bengal sodium I 131

This classification denotes a dye with the molecular formula C20H2Cl4I4O5.2Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 956575SN5L, chemically known as 4,5,6,7-tetrachloro-2,4,5,7-tetraiodofluorescein disodium salt but more generally known as rose bengal sodium, which bears U.S. National Institutes of Health Compound Identifier 69438. European Medicines Agency schedules Rose bengal sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15149MIG.

World Health Organization schedules rose bengal sodium in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: C1=C2C(=C3C=C(C(=O)C(=C3OC2=C(C(=C1I)[O-])I)I)I)C4=C(C(=C(C(=C4Cl)Cl)Cl)Cl)C(=O)[O-].[Na+].[Na+].

UNSPSC 51442436 Rose bengal sodium I 131, a Commodity code, shows little relevant recent activity under state and local procurement. The code nominally describes a radioactive diagnostic imaging agent used in nuclear medicine, but recent opportunities posted under this code do not align with that scope. The Broward County Aviation Department's RFI for Rapiscan X-ray inspection system maintenance services and Pasco County's RFQ for copper sulfate crystals and liquid copper sulfate represent chemical or equipment procurement unrelated to radiopharmaceuticals. State and local buyers do not appear to be actively soliciting rose bengal sodium I 131 or comparable nuclear medicine products through standard procurement channels at present.

Without recent opportunities that match the code's actual commodity definition, geographic spread and issuing-body characterization cannot be meaningfully drawn from posted solicitations. The two recorded opportunities—Broward County Aviation Department's sole-source RFI (due July 28, 2026) and Pasco County's as-needed RFQ (due June 26, 2026)—fall outside the radiopharmaceutical product family entirely and do not signal procurement demand under this code. Monitor for future postings that reflect actual rose bengal sodium I 131 procurement activity from state health departments, hospital systems, or diagnostic imaging centers; current posting activity does not support active pursuit.
