Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its amine functionality and chiral center make it valuable in asymmetric synthesis, especially for developing neurologically active compounds. Commonly employed in the preparation of intermediates for antidepressants, antiviral agents, and central nervous system modulators. Also utilized in research settings for developing novel catalysts and chiral ligands.
