This classification denotes an antihelminthic agent with the molecular formula C22H14Cl2I2N2O2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier EUL532EI54, chemically known as 5-chloro-alpha(sup 4)-(p-chlorophenyl)-alpha(sup 4)-cyano-3,5-diiodo-2,4-salicyloxylidide but generally known as closantel, which bears US NIH Compound Identifier 42574. European Medicines Agency schedules Closantel in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06769MIG.

UNSPSC 51451906 Closantel (Commodity) represents a narrow pharmaceutical product category that state and local governments procure through cooperative purchasing consortia and direct solicitations, though recent activity under this specific code is sparse and does not reflect closantel procurement directly. The source records show pharmaceutical purchasing at the state and county level through piggyback contracts and competitive bidding, but the identified opportunities involve unrelated drugs—doxycycline, ciprofloxacin, and naloxone—rather than closantel, an antiparasitic veterinary and human pharmaceutical. State and local issuing bodies accessing pharmaceutical inventories typically work through established cooperative agreements (such as MMCAP Infuse) or issue standalone RFQs and ITBs for specific therapeutic classes or public-health interventions, with contracts structured as fixed-term agreements with renewal options and quarterly or as-needed delivery schedules.

Recent opportunities show Illinois Department of Public Health and Seminole County, Florida as active pharmaceutical procurers. Illinois awarded a $2,999,999.11 piggyback contract through MMCAP Infuse to Chartwell Rx LLC in August 2026 (IFB 26482DPHPREPDB53392, due September 11, 2026) for a 12-month initial term with two renewal years; Seminole County issued an IFB (IFB60459723LAS, posted June 30, 2026) for naloxone and drug deactivation systems with annual quantities and quarterly deliveries. No recent closantel-specific solicitations appear in the source records, limiting visibility into current demand, pricing, or buyer preferences for this commodity.
