Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of bioactive molecules and organic functional materials. Its aromatic and aldehyde functional group enables condensation reactions to form Schiff bases, which are important in medicinal chemistry for designing antimicrobial, anti-inflammatory, and anticancer agents. Also employed in the preparation of liquid crystals and optoelectronic materials due to its conjugated structure and ability to undergo derivatization.
