Used primarily as an intermediate in the synthesis of antimalarial drugs, particularly in the production of 4-aminoquinoline derivatives like amodiaquine. Its structure allows for modification to enhance pharmacological activity against Plasmodium species. Also investigated for potential applications in anticancer research due to its ability to intercalate DNA and inhibit specific kinases involved in tumor growth. Employed in medicinal chemistry for developing compounds with anti-inflammatory and immunomodulatory properties.
