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 hydroxyl and carbamate functional groups allow for selective modifications, making it valuable in the preparation of beta-amino alcohols and other nitrogen-containing compounds. Commonly employed in asymmetric synthesis routes for drugs targeting the central nervous system and cardiovascular diseases. Also utilized in the preparation of protease inhibitors and other bioactive molecules where enantiomeric purity is essential.
