Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and antidepressants. Its structure supports the creation of bioactive molecules due to the presence of the trifluoromethyl group, which enhances metabolic stability and lipid solubility. Commonly employed in research settings for designing novel compounds with improved pharmacokinetic profiles. Also utilized in the preparation of chiral building blocks for asymmetric synthesis in medicinal chemistry.
