Used as an 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 found in drug candidates targeting inflammatory diseases and cancer. The carboxylic acid and protected amine functional groups allow for selective derivatization, enabling peptide coupling and further chemical modifications in multi-step organic syntheses. Commonly employed in medicinal chemistry for scaffold optimization and structure-activity relationship studies.
