Used primarily in peptide synthesis as a protecting group for lysine residues. It helps prevent unwanted side reactions during the formation of peptide bonds. The Boc (tert-butyloxycarbonyl) group safeguards the amino group, while the DCHA (dicyclohexylamine) salt form enhances solubility and stability. This compound is crucial in the production of complex peptides for research, pharmaceuticals, and biotechnology applications. It ensures precise control over peptide chain assembly, particularly in solid-phase peptide synthesis (SPPS).
