Used as an intermediate in the synthesis of pharmaceuticals, particularly in the preparation of active pharmaceutical ingredients (APIs) where protection of amine groups is required during multi-step reactions. Its carboxylic acid and protected amine functionalities allow for selective coupling and deprotection processes, making it valuable in medicinal chemistry for constructing complex molecules. Commonly employed in the development of anti-inflammatory and central nervous system agents. Also utilized in peptide synthesis and in the creation of specialty polymers requiring precise functional group control.
