Used as a chiral building block in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure serves as a key intermediate in the production of drugs targeting central nervous system disorders, including antidepressants and antipsychotics. The (S)-enantiomer’s specific configuration allows for selective interaction with biological targets, enhancing drug efficacy and reducing side effects. Also employed in the synthesis of agrochemicals and fine chemicals requiring enantiomerically pure amines.
