Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the production of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system (CNS) active drugs. Its enantiomeric purity is critical for ensuring the desired pharmacological activity and minimizing side effects in final drug formulations. Commonly employed in asymmetric synthesis routes where the (R)-configuration contributes to higher binding affinity toward specific neurotransmitter receptors. Also utilized in the development of adrenergic and dopaminergic compounds for treating depression, anxiety, and neurodegenerative disorders.
