Used as a chiral auxiliary in asymmetric synthesis, enabling the selective formation of stereoisomers in pharmaceutical and fine chemical manufacturing. Its structure facilitates high enantioselectivity in alkylation and aldol reactions, making it valuable for producing optically active intermediates. Commonly employed in the development of active pharmaceutical ingredients (APIs) where stereochemical control is critical. After serving its role, it can be removed or recycled, minimizing waste in synthetic routes.
