Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the preparation of active ingredients for anti-inflammatory and analgesic drugs. Its structure allows for easy modification in multi-step reactions, making it valuable in developing beta-keto ester derivatives. Commonly employed in organic synthesis to introduce aromatic ketone functionalities. Also utilized in the production of agrochemicals and fine chemicals where chlorinated aromatic systems are required. Its ester group facilitates coupling reactions and enables further chain elongation in medicinal chemistry applications.
