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 plays a critical role in ensuring high enantiomeric purity of the final drug product, which enhances efficacy and reduces side effects. Commonly employed in asymmetric synthesis routes where the amine group serves as a handle for further functionalization, such as amide coupling or reductive amination. Also utilized in the preparation of bioactive molecules targeting neurological disorders, including antidepressants and anxiolytics. Its hydrochloride salt form improves stability and solubility during manufacturing processes.
