Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anti-inflammatory and analgesic agents. It serves as a building block for more complex organic molecules due to the presence of both ester and aromatic functionalities. Commonly employed in research settings for developing new bioactive compounds and in the preparation of analogs for structure-activity relationship studies. Also utilized in the manufacture of agrochemicals and specialty polymers where chlorinated aromatic esters are required.
