Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active ingredients requiring high enantiomeric purity. Its trifluoromethyl group enhances metabolic stability and lipophilicity, making it valuable in drug design for improved bioavailability and resistance to degradation. Commonly employed in the preparation of agrochemicals and bioactive molecules where stereochemistry plays a critical role in activity. The hydrochloride salt form improves handling, stability, and solubility in aqueous reaction media.
