Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of certain herbicides and fungicides. It serves as a building block in organic reactions due to the presence of both aldehyde and methoxy groups, enabling condensation and substitution reactions. Commonly employed in the preparation of chiral ligands and in the development of active ingredients for crop protection products. Its chloro and methoxy substituents allow for selective functionalization, making it valuable in fine chemical synthesis.
