Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective modification, making it valuable in medicinal chemistry for creating drug candidates targeting cancer, inflammatory diseases, and central nervous system disorders. Commonly employed in solid-phase and solution-phase peptide-like synthesis due to the presence of both carboxylic acid and protected amine functionalities, enabling stepwise assembly of complex molecules. Also utilized in the preparation of PROTACs (proteolysis-targeting chimeras) and other bifunctional compounds where controlled linker incorporation is required.
