Used as a chelating agent in analytical chemistry for the detection and separation of metal ions such as aluminum, iron, and copper due to its ability to form stable complexes. Employed in the synthesis of fluorescent probes and sensors because of its favorable photophysical properties. Acts as a building block in the development of pharmaceuticals and agrochemicals, particularly in compounds with antimicrobial or antifungal activity. Also utilized in materials science for designing metal-organic frameworks (MOFs) and functional coordination polymers.
