Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of fluorinated compounds with enhanced metabolic stability and bioavailability. Its electrophilic carbonyl group allows for nucleophilic addition reactions, making it valuable in building complex organic molecules. Commonly employed in the development of active ingredients for herbicides and fungicides due to the combined effect of chlorine and trifluoromethyl groups, which improve lipophilicity and target binding. Also utilized in medicinal chemistry for constructing fluorinated analogs of biologically active compounds to optimize their pharmacokinetic properties.
