Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of biologically active compounds targeting central nervous system disorders and antidepressants. Its structure supports chirality and polarity important for drug efficacy and metabolic stability. Commonly employed in medicinal chemistry for building blocks in small molecule drugs, especially those requiring fluorinated groups to enhance binding affinity and bioavailability. Also utilized in research for novel enzyme inhibitors due to the electron-withdrawing nature of the trifluoromethyl group.
