Used in the synthesis of pharmaceutical intermediates and fine chemicals, particularly in the development of active pharmaceutical ingredients where aldehyde functionality is required for further derivatization. Its ortho-substituted alkoxy groups enhance reactivity in condensation reactions, making it valuable in the preparation of heterocyclic compounds. Also employed in fragrance chemistry due to its aromatic character, contributing to the creation of complex scent profiles in perfumery. Serves as a building block in organic synthesis for constructing C–C bonds via Wittig or Horner-Wadsworth-Emmons reactions.
