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 aniline moiety allows for selective deprotection under mild acidic conditions, making it valuable in multi-step organic syntheses, especially in peptide chemistry and medicinal chemistry research. The ester group can be hydrolyzed to the corresponding carboxylic acid for further functionalization, enabling its incorporation into more complex molecular architectures. Commonly employed in the preparation of drug candidates targeting central nervous system disorders and inflammatory diseases.
