UNSPSC 51371905: Isomethadone

This classification denotes an opioid receptor agonist with the molecular formula C21H27NO, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 12L95QD6KV, chemically known as 1,1-diphenyl-1-(dimethylaminoisopropyl)butanone-2 but generally known as isomethadone, which bears US NIH Compound Identifier 10072. European Medicines Agency schedules Isomethadone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08323MIG. The term ISOMETHADONE is an International Non-Proprietary Name.

UNSPSC 51371905 Isomethadone is a Commodity code tracking pharmaceutical procurement by state and local health agencies, though recent state and local activity under this code does not align with isomethadone specifically. Seminole County, Florida's recent IFB for naloxone and drug deactivation systems was tagged to this code but represents opioid-reversal and harm-reduction equipment rather than isomethadone stock. The solicitation shows state and local health departments and county health systems buying emergency-response pharmaceuticals and medical safety systems to support community health initiatives, with procurement structured around fixed unit pricing, quarterly delivery cycles, and multi-year terms with renewal options.

Seminole County, Florida is the primary issuing body visible in recent activity under this code. The county's IFB 60459723LAS, posted June 30, 2026 and closed July 26, 2023, sought 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries to the Seminole County Community Health Building in Sanford. Vendors were required to include all shipping and delivery costs in their bids, submit electronically through the county's e-Procurement Portal, maintain workers' compensation and commercial general liability insurance, and comply with E-Verify and drug-free workplace requirements. The contract term was two years with a one-year renewal option, and potential FEMA funding introduced compliance obligations under federal environmental regulations. The procurement does not indicate SBE, MBE, WBE, or other formal set-asides, though it requires vendors to be legally authorized to work in the United States.
