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 in organic reactions where a chloro-substituted ketone functionality is required for further transformation. Commonly employed in Friedel-Crafts acylation and alkylation processes to introduce aromatic ketone groups. Also utilized in the preparation of β-keto esters and other carbonyl-containing compounds in fine chemical manufacturing.
