Used as an intermediate in the synthesis of antimalarial drugs, particularly in the production of compounds related to chloroquine and amodiaquine. It serves as a building block in medicinal chemistry due to the reactivity of both the hydroxyl and chlorine groups, allowing for further functionalization. The compound is also employed in the development of biologically active quinoline derivatives with potential antimicrobial, antifungal, and anticancer properties. Its structure supports participation in cross-coupling reactions, making it valuable in pharmaceutical research and development.
