Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where protected amino groups are required. The Boc-protected amine allows for controlled deprotection during multi-step syntheses, enabling selective reactions without interference from the amine functionality. The carboxylic acid group facilitates coupling reactions, making it valuable in constructing complex organic molecules, especially in medicinal chemistry and drug discovery. Commonly employed in the preparation of peptides and heterocyclic systems where regioselectivity and functional group compatibility are critical.
