Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the development of 4-aminoquinoline derivatives. It exhibits biological activity that contributes to the inhibition of Plasmodium species, the parasites responsible for malaria. Its structure allows for modification to enhance drug efficacy and reduce resistance. Also investigated for potential antiviral and anticancer properties due to its ability to intercalate DNA and interfere with cellular replication processes. Employed in research settings to develop new therapeutic agents targeting infectious and oncological diseases.
