Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules with high enantioselectivity, making it valuable in drug discovery for antidepressants, antipsychotics, and other neurologically active compounds. The amine functionality allows for easy derivatization, enabling rapid generation of compound libraries for screening. Its trifluoromethoxy aromatic group enhances metabolic stability and membrane permeability, beneficial traits in optimizing drug candidates.
