UNSPSC 51301603: Chlorphenesin carbamate

This classification denotes a histamine-1 receptor antagonist with the molecular formula C10H12ClNO4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 57U5YI11WP, chemically known as 1,2-propanediol, 3-(p-chlorophenoxy)-, 1-carbamate (8ci) but more generally known as chlorphenesin carbamate, which bears US NIH Compound Identifier 2724. European Medicines Agency schedules Chlorphenesin carbamate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB01245MIG.

Most nations, for tariff and trade purposes, schedule chlorphenesin carbamate under HS 29094990 and SITC 51617. As of Q4 2014, CHLORPHENESIN CARBAMATE remains US FDA's Preferred Term for this commodity. Chlorphenesin carbamate bears US NLM identifiers UMLS ID C0055467 and NCI Concept Code C65322. SMILES: C1CC(CCC1OCC(COC(=O)N)O)CL.

UNSPSC 51301603 Chlorphenesin carbamate (Commodity) does not align with the recent state and local contract opportunities posted under this code. The two most recent solicitations—the City of Austin's IFB for liquid aluminum sulfate (alum) for wastewater treatment and the City of Tampa's ITB for medical aid supplies—bear no relation to chlorphenesin carbamate, a muscle relaxant pharmaceutical. The code shows little relevant recent activity under its nominal scope.

The mismatch suggests either miscoding by the issuing jurisdictions or that state and local procurement offices are using this Commodity code to tag chemical or medical supply categories more broadly. Until opportunities actually soliciting chlorphenesin carbamate or closely related pharmaceutical muscle relaxants appear in state and local notices, the code does not present a clear procurement signal for vendors in that product line.
