Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and antiviral agents. Its structure supports the construction of complex heterocyclic systems found in bioactive molecules. The Boc-protected amine and carboxylic acid functionalities allow for selective and sequential coupling reactions, making it valuable in solid-phase and solution-phase peptide-like synthesis. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to modulate electronic and steric properties in drug candidates.
