Used as a ligand in coordination chemistry, particularly in catalysis and metal ion chelation due to its ability to form stable complexes with transition metals. It is employed in the development of catalysts for organic transformations such as oxidation and coupling reactions. Also finds use in pharmaceutical research as a building block for bioactive molecules and in the design of metalloenzyme inhibitors. Its structural properties make it valuable in crystal engineering and supramolecular chemistry for constructing functional materials.
