Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antidepressants such as Vilazodone. It plays a key role in constructing active compounds due to the presence of functional groups like the ester and amino moiety, which allow further chemical modifications. Its chloro and ethoxy substituents influence the electronic and steric properties of the aromatic ring, enhancing selectivity and yield in coupling reactions. Commonly employed in research and development for designing new drug candidates with improved bioavailability and metabolic stability.
