Used in the synthesis of pharmaceuticals and fine chemicals, particularly as an intermediate in the production of local anesthetics like lidocaine and other amide-type anesthetics. Serves as a building block in organic synthesis due to the reactivity of the aldehyde group and the electron-donating methoxy groups, which influence regioselectivity in electrophilic substitution reactions. Employed in fragrance and flavor industries for constructing aromatic compounds owing to its pleasant, mild odor. Also utilized in the preparation of liquid crystals and other specialty materials where substituted benzaldehyde derivatives are required.
