Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and antiviral agents. The tert-butoxycarbonyl (Boc) group protects the imidazole nitrogen, allowing selective reactions at the free 6-amino group in multi-step organic syntheses, making it valuable in medicinal chemistry for constructing complex heterocyclic systems. Commonly employed in research settings to prepare bioactive molecules with potential therapeutic applications in oncology and infectious diseases.
