Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of quinoline-based pharmaceuticals. It plays a role in forming complex heterocyclic systems that exhibit biological activity against Plasmodium species. Its carboxylic acid group allows for easy derivatization, enabling the production of amides, esters, and other functional derivatives for drug optimization. Also employed in research for developing new antimicrobial and antiparasitic agents due to the inherent activity of the quinoline scaffold.
