Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification in drug design, making it valuable in medicinal chemistry research. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of protected amine and ester functionalities. Also utilized in the preparation of cyclopropane-containing analogs to enhance metabolic stability and binding affinity in drug candidates.
