UNSPSC 51101905: Chloroquine

This classification denotes an antimalarial agent with the molecular formula C18H26ClN3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 886U3H6UFF, chemically known as 1,4-pentanediamine, n(sup 4)-(7-chloro-4-quinolinyl)-n(sup 1),n(sup 1)-diethyl- but generally known as chloroquine, which bears US NIH Compound Identifier 2719. European Medicines Agency schedules Chloroquine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB06196MIG. The term CHLOROQUINE is an International Non-Proprietary Name.

UNSPSC 51101905 Chloroquine, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal scope. The two opportunities posted under this code in the recent window involve pharmaceutical products entirely unrelated to chloroquine: the Illinois Department of Public Health awarded a piggyback contract through MMCAP Infuse to Chartwell Rx LLC in August 2026 for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets (two antibiotics used for infectious disease treatment), and Seminole County, Florida released an IFB in June 2026 for Naloxone and Safe Drug Deactivation Systems for community health initiatives. Neither solicitation names chloroquine as a line item or describes procurement aligned with the code's stated commodity.

The mismatch between the code's nominal scope and actual buying activity suggests either a tagging error in the state and local procurement system or that chloroquine procurement occurs so rarely at the state and local level that it does not generate consistent solicitations. The two posted opportunities span different issuing bodies (a state health department and a county government) and different geographic regions (Illinois and Florida), but neither is relevant to a firm evaluating chloroquine opportunities under this code. A business development professional should treat this code as inactive for state and local procurement purposes absent direct evidence of a specific chloroquine solicitation from a target jurisdiction.
