Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of non-steroidal anti-inflammatory drugs (NSAIDs) and other bioactive molecules. Its structure allows for easy functionalization, making it valuable in building complex organic compounds. Commonly employed in Friedel-Crafts acylation and halogenation reactions to introduce aromatic ketone functionalities. Also utilized in agrochemical synthesis for developing herbicides and fungicides due to its electron-withdrawing substituents that enhance stability and reactivity.
