UNSPSC 51241248: Methoxsalen or xanthotoxin

This classification denotes a photosensitizing agent and dna crosslinking agent with the molecular formula C12H8O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier U4VJ29L7BQ, chemically known as 9-methoxyfuro(3,2-g)chromen-7-one but generally known as methoxsalen, which bears US NIH Compound Identifier 4114. European Medicines Agency schedules Methoxsalen in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14541MIG.

World Health Organization schedules methoxsalen in its Anatomical Therapeutic Chemical (ATC) Classification. Methoxsalen or xanthotoxin bears US NLM identifiers UMLS ID C0025684 and NCI Concept Code C643. SMILES: O1C2C(CC3C(OC(=O)CC3)C2OC)CC1.

UNSPSC 51241248 Methoxsalen or xanthotoxin is a Commodity code that shows minimal alignment with state and local purchasing activity in the recent-opportunities record. The code nominally denotes a photosensitizing agent used in dermatological treatment, but the two solicitations posted under this code—liquid aluminum sulfate (alum) for wastewater treatment and medical aid supplies for fire rescue operations—bear no relationship to methoxsalen or xanthotoxin. State and local procurement offices appear to have misclassified these opportunities during catalog assignment, signaling either data-entry error or a mismatch between the code's intended scope and the jurisdictions' taxonomic practice. The source provides no evidence of genuine demand for methoxsalen or xanthotoxin under this code among state, county, city, school district, transit authority, or special-purpose district buyers.

The City of Austin posted an IFB for 179,200 gallons of liquid aluminum sulfate with bids due August 25, 2026, and the City of Tampa posted an ITB for medical aid supplies (32 line items across antiseptic sprays, bandages, first aid kits, and related products) with a bid opening originally scheduled for April 9, 2025 but now superseded by the posting date context. Neither opportunity maps to the code's pharmaceutical scope. Absent verifiable recent state and local solicitations for methoxsalen or xanthotoxin itself, this code does not support a pursue decision based on current market activity.
