Used as an intermediate in the synthesis of pharmaceutical compounds, particularly kinase inhibitors. It plays a key role in the development of targeted cancer therapies by enabling selective modification of indazole-based scaffolds. The tert-butyl carbamate (Boc) group protects the nitrogen during peptide coupling or metal-catalyzed reactions, allowing stepwise construction of complex drug molecules. Commonly employed in medicinal chemistry for optimizing potency and metabolic stability in preclinical candidates.
