This chemical is primarily used in peptide synthesis, particularly in the protection of tryptophan residues during the process. The Boc (tert-butyloxycarbonyl) group serves as a temporary protecting group for the amino group, while the Mts (mesitylenesulfonyl) group protects the indole side chain of tryptophan, preventing unwanted reactions. The DCHA (dicyclohexylamine) salt form enhances the stability and solubility of the compound, making it easier to handle and store. It is widely employed in solid-phase peptide synthesis (SPPS) and solution-phase synthesis to produce peptides with high purity and yield. Its application is crucial in the development of pharmaceuticals, bioactive peptides, and research involving peptide-based compounds.
