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 compounds exhibiting biological activity against Plasmodium species. Also employed in the design of fluorescent probes due to its ability to form complexes with metal ions, making it useful in biochemical sensing and imaging. Its structure supports conjugation in medicinal chemistry for creating derivatives with antimicrobial, antiviral, and anticancer properties. Additionally, it finds use in research for developing new heterocyclic compounds with potential therapeutic applications.
