Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of complex organic molecules requiring selective protection of amine groups. Its carboxylic acid and protected amine functionalities allow for sequential coupling reactions, making it valuable in peptide synthesis and medicinal chemistry. The tert-butoxycarbonyl (Boc) group provides stability under various reaction conditions, enabling controlled deprotection when needed. Commonly employed in the preparation of bioactive molecules, including potential drug candidates targeting neurological and inflammatory disorders.
