Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of quinoline-based derivatives that exhibit activity against chloroquine-resistant strains of Plasmodium. Its structure allows for functional modifications that enhance drug efficacy and bioavailability. Also investigated for antimicrobial and anticancer properties due to its ability to intercalate DNA and inhibit specific enzymes in pathogenic cells. Employed in research settings to design novel therapeutic agents targeting parasitic and infectious diseases.
