UNSPSC 51381704 Acetaminophen mercapturate is a Commodity code that shows minimal alignment with recent state and local procurement activity. The code nominally describes a specific pharmaceutical metabolite, but the single recent opportunity tagged to it—Seminole County, Florida's IFB for naloxone and drug deactivation systems—involves finished pharmaceutical products and harm-reduction equipment wholly unrelated to acetaminophen metabolism byproducts. The solicitation does not reference acetaminophen or its derivatives in any form.

Seminole County issued IFB60459723LAS on June 30, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually with a response deadline of July 26, 2023, and quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida. The contract runs two years with an optional one-year renewal, and vendors must provide unit pricing, maintain workers' compensation and general liability insurance, complete E-Verify verification, and comply with FEMA requirements including the Clean Air Act and Federal Water Pollution Control Act. The code shows no other recent state or local opportunities and no identifiable repeat buyer activity or geographic concentration.
