Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Serves as a building block in the preparation of fluorescent dyes and optoelectronic materials due to its conjugated aromatic structure. Employed in research for developing organic semiconductors and photovoltaic devices. Its aldehyde group allows for easy functionalization, enabling the synthesis of Schiff bases and other derivatives for use in coordination chemistry and sensor development. Also explored in photochemical studies owing to its light-sensitive properties.
