Used as a key intermediate in the synthesis of pharmaceuticals, particularly in antimalarial drugs and kinase inhibitors. Its aldehyde functional group allows for easy modification in organic reactions, making it valuable in building complex heterocyclic compounds. Commonly employed in the development of fluorescent dyes and sensors due to its conjugated structure that enhances photophysical properties. Also utilized in coordination chemistry as a ligand precursor for metal complexes with catalytic activity. Found in agrochemical research for designing novel pesticides and herbicides. Its derivatives show potential in materials science for organic semiconductors and optoelectronic devices.
