This classification denotes an antipsychotic agent with the molecular formula C19H18ClNO.CH4O3S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4ZXX17M1C4, chemically known as piperidine 4-(2-chloro-9h-xanthen-9-ylidene)-1-methyl-, methanesulfonate, but more generally known as clopipazan mesylate, which bears US NIH Compound Identifier 43214. European Medicines Agency schedules clopipazan mesylate or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06741MIG.

Most nations, for tariff purposes, schedule clopipazan mesylate under HS 29349990. Clopipazan mesylate bears US NLM identifiers UMLS ID C2825692 and NCI Concept Code C81581. SMILES: CN1CCC(=C2C3CCCCC3OC4C2CC(CC4)CL)CC1.CS(=O)(=O)O.

UNSPSC 51333509 Clopipazan mesilate or mesylate is a Commodity code that covers specialized pharmaceutical products, though recent state and local procurement activity under this code shows minimal alignment with the nominal scope. The single recent opportunity on record—Seminole County, Florida's IFB60459723LAS—solicits naloxone and drug deactivation systems rather than clopipazan mesilate, indicating a significant mismatch between the code's stated pharmaceutical category and what is actually being procured. State and local buyers appear to use this code infrequently or for products outside its intended scope, and the available activity does not establish a clear pattern of demand for the pharmaceutical substance the code nominally describes.

Seminole County posted the naloxone and drug deactivation systems solicitation on June 30, 2026, with a response deadline of July 26, 2023 (note: the due date predates the posting date in the source record, suggesting data inconsistency). The county sought 1,900 units of naloxone and 800 safe drug deactivation systems annually through competitive bidding, with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. The contract included a two-year initial term with a one-year renewal option and required vendors to meet standard compliance obligations including drug-free workplace certification, E-Verify confirmation, and relevant insurance coverage. The procurement carried no explicit set-aside designations and was potentially funded through FEMA. Beyond this single Seminole County opportunity, the code shows no recent activity among other state agencies, counties, cities, school districts, transit authorities, or special-purpose districts.
