Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules and peptide-based drugs. Its structure allows for selective modification and coupling reactions, making it valuable in medicinal chemistry for building complex organic molecules. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of both carboxylic acid and protected amine functionalities. The thiophene ring can enhance binding affinity in certain biological targets, contributing to the design of enzyme inhibitors or receptor modulators.
