Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of quinoline-based pharmaceuticals. It serves as a building block for modifying the quinoline core to enhance biological activity against Plasmodium species. Also employed in research for developing new antimicrobial and anticancer agents due to its ability to chelate metal ions and interact with biological targets. Its derivatives are explored for their potential in treating inflammatory diseases and neurodegenerative disorders.
