Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antimalarial and antibacterial agents. Exhibits antimicrobial properties and has been studied for use in disinfectants and preservatives. Applied in research settings for developing new quinoline-based drugs due to its ability to chelate metal ions, which can enhance biological activity. Also explored for its potential in treating neurodegenerative diseases because of metal-chelating and antioxidant effects.
