UNSPSC 51451907: Niclosamide

This classification denotes an antihelminthic agent with the molecular formula C13H8Cl2N2O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 8KK8CQ2K8G, chemically known as 2,5-dichloro-4-nitrosalicylanilide but generally known as niclosamide, which bears US NIH Compound Identifier 4477. European Medicines Agency schedules Niclosamide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09230MIG.

UNSPSC 51451907 Niclosamide is a Commodity code that should identify purchases of a specific antihelmintic pharmaceutical agent, yet the recent state and local opportunities tagged under this code show no procurement activity for niclosamide itself. Instead, the tagged records describe purchases of unrelated pharmaceutical products — Doxycycline Hyclate and Ciprofloxacin Hydrochloride antibiotics through a piggyback contract, and Naloxone with drug deactivation systems through a county health procurement. State and local issuing bodies appear to use this code inconsistently or incorrectly when purchasing other pharmaceutical supplies. The code shows little relevant recent activity aligned with its nominal scope.

Illinois Department of Public Health completed a $2,999,999.11 piggyback pharmaceutical warehouse contract awarded to Chartwell Rx LLC through the MMCAP Infuse consortium in August 2026 covering antibiotic supplies, and Seminole County, Florida released an IFB in June 2026 (response due July 26, 2026) for 1,900 units of Naloxone and 800 safe drug deactivation systems annually, with quarterly deliveries required. Neither solicitation involves niclosamide procurement. Business development professionals should verify code assignment with issuing bodies before committing resources, as the mislabeling suggests either data-quality issues in the procurement database or a significant divergence between the code's intended scope and actual purchasing patterns.
