Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) requiring piperidine scaffolds. Its protected amine group and carboxylic acid functionality make it valuable in peptide coupling and heterocyclic chemistry. Commonly employed in medicinal chemistry for constructing modulators of central nervous system targets and kinase inhibitors. The Boc-protected amine allows for selective deprotection under mild acidic conditions, enabling stepwise assembly of complex molecules in multi-step syntheses.
