Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. It plays a key role in the production of selective norepinephrine reuptake inhibitors, which are important for treating depression and attention deficit hyperactivity disorder (ADHD). Due to its chiral structure, it enables the creation of enantiomerically pure drugs, improving efficacy and reducing side effects. Commonly employed in research and development for novel psychotropic medications.
