UNSPSC 51441603: Fluorescein

This classification denotes a contrast agent, a preparation that US FDA recognizes as an active ingredient or moiety under Unique Ingredient Identifier TPY09G7XIR. The European Medicines Agency schedules Fluorescein sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13905MIG. Fluorescein generally arises in the molecular formula C20H12O5. The term 'fluorescein' is an International Nomenclature of Cosmetic Ingredients designation. SMILES: O1C2C(C(C3C1CC(=O)CC3)C1C(CCCC1)C(=O)O)CCC(O)C2.

UNSPSC 51441603 Fluorescein is a Commodity code that shows minimal recent state and local procurement activity aligned with its nominal scope. The two most recent opportunities posted under this code involve X-ray system maintenance services (Broward County Aviation Department) and copper sulfate supply (Pasco County, Florida) — neither of which is fluorescein procurement. State and local governments appear to use this code infrequently or to tag purchases that fall outside the fluorescein category proper. No recent solicitations for fluorescein itself appear in the posting record.

Broward County Aviation Department issued an RFI (Request for Information) on June 25, 2026, with responses due July 28, 2026, to challenge or validate a proposed sole-source designation for Rapiscan X-ray inspection system maintenance services. Pasco County released an RFQ on June 3, 2026, with proposals due June 26, 2026, for as-needed supply of large copper sulfate crystals and liquid copper sulfate under an indefinite-quantity arrangement. Both opportunities are located in Florida, but neither represents fluorescein procurement. Given the mismatch between the code's nominal scope and the recent opportunities actually posted, this code does not presently signal active state and local demand for fluorescein products.
