Used primarily in organic synthesis as an intermediate for pharmaceuticals and functional materials. Acts as a Schiff base ligand in coordination chemistry, forming complexes with metal ions that exhibit catalytic or antimicrobial properties. Also investigated for its potential in optoelectronic applications due to its conjugated structure and ability to undergo intramolecular charge transfer. Shows promise in dye-sensitized solar cells and as a building block for liquid crystal compounds. Some derivatives display biological activity, making them relevant in medicinal chemistry research.
