Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective protection of amine groups during multi-step organic reactions, making it valuable in drug discovery and medicinal chemistry. Commonly employed in the preparation of protease inhibitors and central nervous system agents due to its stability and ease of deprotection under mild conditions. Also utilized in the construction of complex heterocyclic systems where controlled reactivity is required.
