Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structural configuration makes it valuable in asymmetric synthesis, helping to control the formation of specific enantiomers in drug molecules. Commonly employed in the preparation of protease inhibitors and other bioactive compounds requiring defined stereocenters. Also utilized as a specialty solvent or catalyst intermediate in fine chemical manufacturing due to its amine functionality and conformational stability.
