Used as an 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 in drug design, making it valuable in medicinal chemistry for creating targeted therapies. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of carboxylic acid and protected amine functionalities. Also utilized in the preparation of thiophene-based heterocyclic compounds for research in organic electronics and materials science.
