Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and certain antimicrobial agents. Its structure allows for selective functionalization, making it valuable in building complex organic molecules. Commonly employed in research and development of bioactive compounds due to the presence of reactive aldehyde and electron-withdrawing chlorine groups. Also utilized in agrochemical synthesis for developing herbicides and plant growth regulators. Its methoxy and halogen substituents enhance stability and influence binding affinity in target molecules.
