Used in peptide synthesis as a protecting group for amino acids, specifically for the amino group of cyclohexylalanine (Cha). It helps prevent unwanted reactions during the formation of peptide bonds. Commonly employed in solid-phase peptide synthesis (SPPS) to ensure selective deprotection and coupling steps. Its stability under acidic conditions makes it suitable for complex peptide assembly. Also utilized in the development of pharmaceuticals and bioactive peptides, where precise control over amino acid sequences is critical. Its removal is typically achieved under mild acidic conditions, preserving the integrity of the peptide chain.
