Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require a protected diazepine ring. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in the preparation of kinase inhibitors and other bioactive compounds where nitrogen-containing heterocycles are essential. The tert-butyl carbamate (Boc) group provides stability and controlled deprotection during multi-step syntheses, enhancing yield and purity in drug manufacturing processes.
