UNSPSC 51303001: Flucytosine

This classification denotes a pyrimidine antagonist with the molecular formula C4H4FN3O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier D83282DT06, chemically known as 2(1h)-pyrimidinone, 4-amino-5-fluoro- (8ci)(9ci) but generally known as flucytosine, which bears US NIH Compound Identifier 3366. European Medicines Agency schedules Flucytosine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07676MIG.

UNSPSC 51303001 Flucytosine is a Commodity code that shows a fundamental mismatch between its nominal scope and recent state and local procurement activity. The code nominally covers flucytosine, an antifungal pharmaceutical, yet the recent opportunities posted under this code involve unrelated product categories: liquid aluminum sulfate for municipal wastewater treatment and medical aid supplies for fire rescue operations. Neither solicitation concerns flucytosine or pharmaceutical procurement, and there is no evidence of active state and local buying under the code's stated scope.

The two posted opportunities—Austin's IFB 2200 CSH1061 for wastewater treatment chemicals (due August 25, 2026) and Tampa's ITB 25-P-00157 for medical and first aid supplies (due April 9, 2025)—appear to be miscoded at source rather than representative of legitimate activity under this Commodity code. State and local procurement professionals should treat this code as inactive for flucytosine and flag the underlying opportunities as category-coding errors in their respective jurisdictions' procurement systems.
