Used as a key chiral intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) agents. Its structure supports the creation of bioactive molecules with high enantioselectivity, making it valuable in the production of antidepressants and antipsychotic drugs. The presence of trifluoromethoxy and methoxy groups enhances metabolic stability and binding affinity to target receptors. Commonly employed in asymmetric synthesis routes where the R-enantiomer provides desired biological activity. Widely utilized in medicinal chemistry research for lead optimization and drug candidate development.
