UNSPSC 51101665: Melarsomine

This classification denotes an antihelminthic agent with the molecular formula C13H21AsN8S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 374GJ0S41A, chemically known as bis(2-aminoethyl) p-((4,6-diamino-s-triazin-2-yl)amino)dithiobenzenearsonite but generally known as melarsomine, which bears US NIH Compound Identifier 65962. European Medicines Agency schedules Melarsomine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08719MIG.

UNSPSC 51101665 Melarsomine, a Commodity code, shows little relevant recent state and local procurement activity. The two opportunities in the source block are unrelated to melarsomine — a parasiticide veterinary pharmaceutical — and instead document procurements of antibiotics (doxycycline and ciprofloxacin) and naloxone with drug deactivation systems. The code's nominal scope does not align with what is actually being solicited under these tagged opportunities, signaling either a tagging error in the source data or a code assignment that diverges substantially from current buying patterns.

The Illinois Department of Public Health awarded a completed piggyback pharmaceutical contract through MMCAP Infuse to Chartwell Rx LLC on August 28, 2026, totaling $2,999,999.11 over the life of the contract with renewal options, while Seminole County, Florida released an Invitation for Bid in June 2026 for naloxone and drug deactivation systems with annual requirements of 1,900 units and 800 units respectively and quarterly deliveries to the Seminole County Community Health Building. Without open solicitations or active opportunities explicitly tagged to melarsomine procurement, this code warrants a watch posture rather than active pursuit at this time.
