Used as a chelating ligand in coordination chemistry, particularly in the formation of metal complexes with transition metals such as nickel, copper, and cobalt. Its bidentate structure allows it to stabilize metal ions in catalytic systems, making it useful in homogeneous catalysis. It is also employed in the development of luminescent complexes and sensors due to its ability to influence the electronic properties of metal centers. Additionally, it serves as a building block in supramolecular chemistry for constructing molecular architectures like grids and cages.
