Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where protection of amine groups is required. Its structure allows for selective deprotection under mild conditions, making it valuable in multi-step organic syntheses. Commonly employed in the preparation of peptide-based drugs and kinase inhibitors due to its stability and compatibility with various reaction conditions. Also utilized in medicinal chemistry for constructing complex nitrogen-containing heterocycles.
