UNSPSC 51273602: Vinyl ether

This classification denotes an anesthetic with the molecular formula C4H6O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2H2T044E11, chemically known as 1,1-oxybisethene but generally known as vinyl ether, which bears US NIH Compound Identifier 8024. European Medicines Agency schedules Vinyl ether in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15697MIG. World Health Organization schedules vinyl ether in its Anatomical Therapeutic Chemical (ATC) Classification.

As of Q4 2014, VINYL ETHER remains the US FDA Preferred Term for this commodity. SMILES: C=COC=C.

UNSPSC 51273602 Vinyl ether (Commodity) does not align with the recent state and local procurement activity tagged under this code. Seminole County, Florida posted IFB 60459723LAS on June 30, 2026, to procure 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually — a pharmaceutical and medical device procurement bearing no relationship to vinyl ether, a chemical solvent and anesthetic. The mismatch suggests either a data-entry error in the county's classification system or a misuse of the code by the issuing body.

The code shows no recent state and local opportunities for vinyl ether itself. Business development professionals should treat this code as inactive in state and local procurement, or verify with target customers that they use alternative classification schemes, cooperative purchasing catalogs, or vendor-neutral language when sourcing industrial chemicals and anesthetic compounds.
