Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports the construction of complex heterocyclic systems, making it valuable in medicinal chemistry for drug discovery. The amine and ester functionalities allow for versatile chemical modifications, enabling the formation of amides, sulfonamides, and other derivatives important in optimizing drug potency and selectivity. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to its stability and reactivity profile.
