Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its primary application lies in the production of central nervous system (CNS) agents, including antidepressants and antipsychotics, where the (R)-enantiomer provides desired biological activity. The amine functionality allows for easy derivatization, making it valuable in medicinal chemistry for constructing complex molecules. It is also employed in the preparation of catalysts for asymmetric synthesis, enhancing the efficiency and selectivity of chemical reactions in drug manufacturing.
