Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports the introduction of trifluoromethyl-containing aromatic groups, which can enhance metabolic stability and binding affinity in drug candidates. Commonly employed in solid-phase and solution-phase peptide synthesis due to the presence of both carboxylic acid and protected amine functionalities. The Boc-protected amine allows for controlled deprotection and further coupling steps, making it valuable in multi-step organic syntheses targeting complex therapeutic agents.
