Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant drugs. Its structural configuration allows for effective interaction with neurotransmitter transporters, making it valuable in central nervous system drug research. It is also employed in the preparation of chiral ligands and catalysts for asymmetric synthesis in medicinal chemistry. Due to its amine functionality, it readily participates in coupling reactions, enabling the construction of complex bioactive molecules.
