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. Its hydroxyl and carbamate functional groups allow for selective modifications, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of beta-amino alcohols and other nitrogen-containing compounds with biological activity. The presence of the allyl group enables further transformations such as cross-metathesis or epoxidation, enhancing its utility in medicinal chemistry and drug discovery.
