Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated compounds with enhanced metabolic stability and bioavailability. Its ethynyl and chloro functional groups allow for further chemical modifications through coupling reactions, making it valuable in building complex organic molecules. Commonly employed in the preparation of active ingredients in crop protection agents and in medicinal chemistry for targeting specific enzymes or receptors. The presence of trifluoromethyl group contributes to increased lipophilicity and binding affinity in biologically active compounds.
