Used as a chiral intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its stereochemistry and functional groups allow for selective reactions, making it valuable in asymmetric synthesis. Commonly employed in the preparation of active pharmaceutical ingredients (APIs) where precise spatial arrangement is critical for biological activity. The silyl protecting group enhances stability during multi-step reactions and can be selectively removed under mild conditions, enabling efficient synthetic routes in drug discovery and process chemistry.
