Used as a fluorescent probe in analytical chemistry due to its strong emission properties in the presence of specific metal ions, particularly aluminum and zinc. Its structure allows for selective binding and signal enhancement, making it valuable in environmental monitoring and biological imaging. Also serves as an intermediate in the synthesis of pharmaceuticals and agrochemicals, where the quinoline core contributes to bioactivity. Exhibits antimicrobial properties in some formulations, supporting its use in research for developing new therapeutic agents.
