UNSPSC 51313706 Bosentan hydrate (Commodity) shows minimal recent state and local procurement activity aligned to its nominal pharmaceutical scope. The single recent opportunity posted under this code — Seminole County, Florida's IFB60459723LAS for Naloxone and Safe Drug Deactivation Systems — appears misclassified, as naloxone and drug deactivation equipment fall outside the bosentan hydrate product category. Bosentan hydrate is an endothelin-receptor antagonist used in pulmonary hypertension treatment; the Seminole County solicitation targets emergency-response pharmaceuticals and harm-reduction equipment for community health initiatives, which represents a distinct therapeutic and operational domain.

The Seminole County IFB, posted June 30, 2026 with a response deadline of July 26, 2023, sought 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. The contract includes a two-year initial term with one-year renewal option and requires electronic bid submission through the county's e-Procurement Portal, with vendors absorbing shipping and delivery costs. Bidders must provide unit pricing, maintain workers' compensation and commercial general liability insurance, achieve E-Verify compliance, and comply with federal regulations including the Clean Air Act and Federal Water Pollution Control Act, with potential FEMA funding implications. The code shows no meaningful recent state and local solicitation activity for bosentan hydrate itself; vendors pursuing this Commodity should flag the classification mismatch and monitor for corrected future postings.
