Used as a protected intermediate in peptide synthesis, particularly for incorporating modified amino acids into peptide chains. The bis-tert-butoxycarbonyl (Boc) groups provide orthogonal protection for the amino functionality, allowing selective deprotection under mild acidic conditions without affecting other sensitive groups. The pyridine ring can act as a coordinating moiety in catalysis or as a structural element in bioactive molecule design. Commonly employed in the development of pharmaceuticals and enzyme inhibitors where precise functional group control is required during multi-step synthesis.
