Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in constructing complex organic molecules for drug discovery. Commonly employed in peptide coupling reactions and solid-phase synthesis due to the presence of both amino and carboxylic acid groups, with the Boc-protected amine enabling controlled deprotection and stepwise assembly. Also utilized in the preparation of enzyme inhibitors and receptor modulators in medicinal chemistry research.
