Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating potent and targeted drug candidates. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of both carboxylic acid and protected amine functionalities. Also utilized in the preparation of heterocyclic compounds with biological activity, including antiviral and anti-inflammatory agents.
