Used as a key intermediate in the synthesis of advanced organic materials, particularly in the preparation of Schiff base ligands and coordination polymers. Its dual aldehyde functionality allows for condensation reactions with diamines to form bis-Schiff bases, which are valuable in catalysis and sensor development. Also employed in the design of porous organic frameworks due to its rigid aromatic structure and ability to promote network formation. Shows potential in optoelectronic applications when incorporated into conjugated systems.
