Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of dyes and fluorescent probes due to its electron-donating substituents. Its aldehyde group allows for easy functionalization in condensation reactions, making it valuable in creating Schiff bases and other conjugated systems. Also employed in the preparation of nonlinear optical materials and as a building block in organic synthesis where amino and methoxy groups enhance reactivity and solubility.
