It is primarily used as a chelating agent in coordination chemistry, forming stable complexes with various metal ions. These complexes are often employed in catalytic processes, particularly in organic synthesis, where they enhance reaction efficiency and selectivity. Additionally, it serves as a ligand in the development of luminescent materials, which are applied in sensors and optoelectronic devices. Its ability to bind metals also makes it useful in analytical chemistry for the detection and quantification of specific ions. Furthermore, it finds application in biochemical research for studying metal-protein interactions and enzyme mechanisms.
