UNSPSC 51332815: Mesoridazine

This classification denotes a dopamine antagonist and antipsychotic agent with the molecular formula C21H26N2OS2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 5XE4NWM740, chemically known as 10h-phenothiazine, 10-(2-(1-methyl-2-piperidinyl)ethyl)-2-(methylsulfinyl)- but generally known as mesoridazine, which bears US NIH Compound Identifier 4078. European Medicines Agency schedules Mesoridazine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08786MIG.

UNSPSC 51332815 Mesoridazine is a Commodity code, but the recent state and local procurement activity tagged under it does not reflect pharmaceutical inventory for psychiatric or behavioral health treatment. Instead, Seminole County, Florida has posted the only recent opportunity under this code—an IFB for Naloxone and Safe Drug Deactivation Systems—which represents emergency response and harm-reduction supplies rather than prescription antipsychotic medications. The mismatch between the code's nominal scope and actual buying signal suggests this code sees minimal relevant activity in state and local procurement. Seminole County's solicitation targets annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. Vendors must submit bids electronically through the county's e-Procurement Portal, include all shipping and delivery costs in their proposals, hold appropriate insurance coverage (workers' compensation, commercial general liability, and professional liability), and comply with E-Verify requirements and drug-free workplace certification. The contract carries an initial two-year term with a one-year renewal option and includes a three-month probationary period.

The solicitation, posted June 30, 2026, with a response deadline of July 26, 2023, represents the only documented recent state and local procurement under this code. No set-aside designations for disadvantaged enterprises are specified. The procurement may be FEMA-funded, introducing additional federal compliance requirements including the Clean Air Act and Federal Water Pollution Control Act, with contractors subject to audits and record inspections. The geographic footprint is limited to Florida based on available recent activity. Business development professionals should note that this code does not appear to be actively used for mesoridazine or related antipsychotic medications in state and local purchasing; procurement teams seeking to pursue pharmaceutical supply contracts should verify the correct UNSPSC classification before investing significant bid preparation effort.
