Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its functional groups allow for selective modifications in multi-step organic reactions, making it valuable in medicinal chemistry. Commonly employed in peptide coupling and protection strategies due to the presence of both carboxylic acid and Boc-protected amine groups. Also utilized in the preparation of heterocyclic compounds through cyclization reactions, especially in the construction of benzoxazole and quinazoline derivatives.
