Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Serves as a building block in the preparation of bioactive compounds, particularly in the development of potential drug candidates targeting inflammation and central nervous system disorders. Also applied in the synthesis of conjugated organic molecules for optoelectronic materials due to its aromatic and electron-rich structure. Its aldehyde group allows for easy functionalization via condensation or reduction reactions, enabling diverse derivatization for research in medicinal and materials chemistry.
