Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of anti-inflammatory and analgesic agents. It plays a key role in constructing active ingredients that contain substituted phenylalkyl structures. Commonly utilized in the development of non-steroidal anti-inflammatory drugs (NSAIDs) due to its ability to facilitate carbon-carbon bond formation in aromatic systems. Also employed in the preparation of agrochemicals and specialty organic compounds where chloro ketone functionality is required for further transformation.
