Used in pharmaceutical synthesis as a chiral building block for developing active pharmaceutical ingredients, particularly in the production of drugs targeting central nervous system disorders. Its enantiomerically pure structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy and safety. Also employed in the development of serotonin and norepinephrine reuptake inhibitors due to its structural similarity to known bioactive amines. Commonly utilized in research settings for structure-activity relationship studies involving phenyl-substituted amine derivatives.
