Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure supports the development of enzyme inhibitors and receptor modulators due to the presence of the difluoromethyl group, which enhances metabolic stability and binding affinity. Commonly employed in the production of antidiabetic and antiviral agents, where chirality plays a critical role in drug efficacy. The hydrochloride salt form improves solubility and handling in aqueous reaction environments.
