Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating drug candidates with improved stability and binding properties. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of orthogonal protecting groups. Also utilized in the preparation of proteolysis-targeting chimeras (PROTACs) and other targeted therapies.
