Used as a key intermediate in the synthesis of antimalarial drugs, particularly in the production of quinolone-based pharmaceuticals. It serves as a ligand in coordination chemistry for developing metal complexes with catalytic activity. Also applied in the preparation of fluorescent probes due to its strong chelating and photophysical properties, useful in bioimaging and sensor technologies. Additionally, it acts as a building block in organic synthesis for creating biologically active molecules, including antimicrobial and anticancer agents.
