This chemical is widely used in peptide synthesis as a protecting group for aspartic acid. The Boc (tert-butyloxycarbonyl) group safeguards the amino functionality, while the OMe (methoxy) group protects the carboxyl side chain, ensuring selective reactions during peptide chain assembly. The DCHA (dicyclohexylamine) salt form enhances stability and solubility, making it easier to handle in organic solvents. It is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase synthesis, enabling the production of complex peptides with high purity. Its application is crucial in pharmaceutical research, especially in developing peptide-based drugs and bioactive compounds.
