Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active compounds. Its stereochemistry enables high enantioselectivity in drug formulations, improving efficacy and reducing side effects. Commonly employed in medicinal chemistry for constructing bioactive molecules with improved metabolic stability and receptor binding affinity. Also utilized in research settings for exploring structure-activity relationships in heterocyclic amine derivatives.
