Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of enantiomerically pure drugs. Its chiral amine functionality makes it valuable in asymmetric synthesis and as a resolving agent for racemic mixtures. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in drug efficacy and safety. Also utilized in the manufacture of agrochemicals and fine chemicals requiring high optical purity.
