Used primarily in coordination chemistry as a ligand for metal ions, particularly in the synthesis of metal complexes. Its structure allows it to bind effectively to metals, making it useful in catalysis and material science. It is also employed in the development of luminescent materials and sensors due to its ability to form stable complexes with transition metals. Additionally, it finds application in biochemical research for studying metal-protein interactions and enzyme mechanisms. Its unique properties make it a valuable tool in designing new compounds with specific electronic or optical characteristics.
