Chloroquine serves primarily as an active pharmaceutical ingredient in antimalarial drug formulations, where it interferes with the parasite's ability to metabolize hemoglobin within red blood cells. It is also employed in research synthesis as a reference compound for investigating lysosomal function and autophagy inhibition, and as a starting material or intermediate in the production of related quinoline-based drug substances.

Chloroquine is supplied in solid form to pharmaceutical-grade specifications aligned with Ph.Eur. and relevant national pharmacopeial standards.
