UNSPSC 51451905 Clorsulon is a Commodity code that encompasses pharmaceutical active ingredients and specialty drug compounds procured by state and local health agencies. Recent state and local solicitations under this code show procurement of pharmaceutical products and medical supplies—including antibiotics, opioid-reversal agents, and drug deactivation systems—to support public health missions at the state and county level. The buying pattern reflects health departments and county public health offices acquiring pharmaceutical inventory and medical countermeasures through piggyback contracts, competitive bidding, and cooperative purchasing vehicles. Issuing bodies include state departments of public health and county health departments seeking to stock emergency and preventive medications for distribution to community health facilities and emergency response programs.

Activity under this code appears concentrated in the South and Midwest. The Illinois Department of Public Health awarded a $2,999,999.11 pharmaceutical contract to Chartwell Rx LLC through the MMCAP Infuse cooperative purchasing vehicle (IFB, completed award August 28, 2026) for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets with a 12-month initial term and two one-year renewal options. Seminole County, Florida released an IFB (posted June 30, 2026; due July 26, 2023) seeking 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually with quarterly deliveries to the Seminole County Community Health Building, on a fixed-fee basis with a two-year initial term and one-year renewal option. Both opportunities required vendors to meet drug-free workplace certification, E-Verify compliance, and specified insurance coverage. The Illinois award was not set-aside-restricted; the Florida procurement noted potential FEMA funding with associated federal compliance requirements.
