Used primarily as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of central nervous system (CNS) active agents. Its enantiomeric purity makes it valuable in asymmetric synthesis, where it serves as an intermediate in the development of antidepressants, antipsychotics, and other neurologically targeted drugs. It is also employed in the preparation of agrochemicals and fine chemicals requiring stereochemical control. Due to its amine functionality and chiral center, it participates in reductive amination and nucleophilic addition reactions, enabling the construction of complex molecular architectures in medicinal chemistry.
