Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where substituted benzaldehydes are required. It serves as a building block in the development of agrochemicals, including certain herbicides and fungicides, due to its reactive aldehyde and chlorine groups. Also employed in the fragrance industry for the preparation of aromatic compounds, contributing to the creation of complex scent molecules in perfumes and flavorings. Its methoxy and chloro substituents allow for selective reactions in organic synthesis, making it valuable in research and development of fine chemicals.
