Used as a fluorescent probe in analytical chemistry due to its strong chelating ability with metal ions, particularly aluminum, zinc, and iron. Its fluorescence intensifies upon binding to these metals, making it valuable in sensors and detection systems for environmental monitoring and biological imaging. Also employed in the development of photoluminescent materials and coordination polymers for use in optoelectronic devices. Additionally, it serves as a ligand in catalytic reactions, enhancing selectivity and efficiency in metal-catalyzed transformations.
