Used as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of pharmaceuticals targeting cancer and inflammatory diseases. Its protected amine group allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. Commonly employed in solid-phase and solution-phase peptide-like synthesis where stability and selective deprotection are required. Also utilized in the preparation of nucleoside analogs and as a scaffold in drug discovery for optimizing potency and metabolic stability.
