Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of local anesthetics and anti-inflammatory agents. It serves as a building block in the development of active pharmaceutical ingredients due to its reactive aldehyde and substituent groups that facilitate further chemical modifications. Also employed in the preparation of agrochemicals and dyes, where its chloro and methoxy functionalities contribute to the desired biological or optical properties. Its structural features make it valuable in organic synthesis for constructing more complex aromatic compounds.
