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 nominally covers chemical compounds used in medical diagnostics and industrial applications, but the recent state and local solicitations tagged under this code show minimal alignment with fluorescein itself. The four most recent opportunities reflect procurement of radiologic and X-ray equipment, extended warranty services for imaging systems, maintenance service plans for specialized inspection equipment, and copper sulfate chemicals — none of which are fluorescein products. State and local governments are using this code to purchase medical imaging equipment installation (Maricopa County), imaging system warranty renewals (Escambia County Correction), proprietary X-ray inspection system maintenance services (Broward County Aviation), and unrelated chemical supplies (Pasco County). The issuing bodies span county governments, county corrections departments, and county aviation authorities across Florida and Arizona.

Geographic activity centers on Florida, with three of the four recent opportunities posted by Escambia County Correction, Broward County Aviation, and Pasco County, alongside one Arizona solicitation from Maricopa County. The most recent opportunity is Maricopa County's IFB 362910, posted October 1, 2026, with responses due October 22, 2026, for radiologic equipment and installation at three colleges. Escambia County Correction posted a sole-source warranty renewal (SSCORALM2526005) on August 12, 2026, due August 19, 2026, for X-Ray machine extended warranty coverage. The code shows little relevant recent activity tied to its nominal fluorescein classification, suggesting that either the tagging is systematic misclassification or fluorescein procurement through state and local channels is sparse enough to be masked by unrelated commodity captures in the same code.
