Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure allows for selective protection of amine groups during multi-step organic syntheses, making it valuable in peptide chemistry and medicinal research. The carboxylic acid and protected amine functionalities enable coupling reactions, facilitating the construction of complex molecules in drug discovery. Commonly employed in solid-phase synthesis and used to introduce benzoic acid derivatives into target compounds with high purity and yield.
