UNSPSC 51311810: Clemizole undecylate

This classification denotes a histamine-1 receptor antagonist with the molecular formula C19H20ClN3.C11H22O2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6K5XAP3A37, chemically known as 1h-benzimidazole, 1-((4-chlorophenyl)methyl)-2-(1-pyrrolidinylmethyl)-, monoundecanoate, but more generally known as clemizole undecylate, which bears US NIH Compound Identifier 656650. European Medicines Agency schedules clemizole undecylate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06650MIG.

Most nations, for tariff purposes, schedule clemizole undecylate under HS 29339990. Clemizole undecylate bears US NLM identifiers UMLS ID C3273573 and NCI Concept Code C97695. SMILES: CCCCCCCCCCC(=O)O.C1CCC2C(C1)NC(N2CC3CCC(CC3)CL)CN4CCCC4.

UNSPSC 51311810 Clemizole undecylate, a Commodity code, shows minimal alignment between its nominal scope and recent state and local procurement activity. The three recent opportunities tagged under this code involve naloxone and drug deactivation systems, therapeutic pharmacy initiatives and direct-to-manufacturer prescription programs, and generic multi-source pharmaceuticals and OTC products—none of which are clemizole undecylate or closely related pharmaceutical compounds. The code appears to be misapplied across these solicitations, suggesting either tagging errors in the source systems or a departure from the code's intended pharmaceutical scope in current state and local buying patterns.

Recent activity spans Seminole County, Florida (an IFB for naloxone and safe drug deactivation systems with a July 26, 2023 response deadline), the Texas Health and Human Services Commission (an RFI on direct-to-manufacturer prescriptions posted April 3, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance (an RFP for generic pharmaceuticals and OTC products due March 26, 2026, serving multiple state and local government facilities including Oregon). No opportunities specifically requesting clemizole undecylate or products within the code's defined scope have been identified in the recent record. Until state and local procurement offices begin tagging clemizole-specific solicitations or related pharmaceutical compounds correctly, this code presents no clear market activity worth pursuing.
