UNSPSC 51151667: Tridihexethyl

This classification denotes an antimuscarinic agent with the molecular formula C21H36NO, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 7HE50A367X, chemically known as benzenepropanaminium, gamma-cyclohexyl-n,n,n-triethyl-gamma-hydroxy-, chloride but generally known as tridihexethyl, which bears US NIH Compound Identifier 20298. European Medicines Agency schedules Tridihexethyl in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB04951MIG.

UNSPSC 51151667 Tridihexethyl is a Commodity code, but the recent state and local opportunities posted under it do not align with tridihexethyl procurement — instead, they reflect solicitations for naloxone, drug deactivation systems, and pharmacy benefit program services. The code shows a mismatch between its nominal scope and the work actually being tagged under it in state and local systems. The two recent opportunities span different issuing bodies and procurement mechanisms: Seminole County, Florida posted an IFB for naloxone and safe drug deactivation systems (1,900 units of naloxone and 800 deactivation systems annually), and the Texas Health and Human Services Commission issued a Request for Information to explore vendor capabilities for direct-to-manufacturer prescription fulfillment programs. Neither solicitation involves the specific chemical compound the code nominally describes.

Activity under this code appears limited and geographically sparse, with recent postings only in Florida and Texas. Seminole County's naloxone and deactivation systems IFB closed July 26, 2023, and required quarterly deliveries to the Seminole County Community Health Building in Sanford, with pricing on a fixed-fee basis; the Texas HHS RFI, posted April 3, 2026, had an immediate April 3, 2026 response deadline and served as exploratory market research rather than a competitive procurement vehicle. The mismatch between the code's nominal chemical scope and these health services solicitations suggests that firms tracking this code for tridihexethyl procurement should verify coding accuracy before submitting, or monitor whether the code assignment changes as posting practices evolve.
