Used as a ligand in coordination chemistry, particularly in the synthesis of metal complexes for catalytic applications. Its structure allows chelation of metal ions, enhancing stability and selectivity in catalytic reactions. Employed in the development of sensors due to its ability to bind metal ions with high specificity. Also explored in supramolecular chemistry for designing molecular receptors and host-guest systems. Shows potential in polymer chemistry as a cross-linking agent or modifier to influence thermal and mechanical properties.
