This chemical is widely used in peptide synthesis as a protecting group for aspartic acid. It helps in preventing unwanted side reactions during the formation of peptide bonds. The Boc (tert-butyloxycarbonyl) group provides stability under acidic conditions, while the methoxy ester protects the carboxyl group. It is particularly useful in solid-phase peptide synthesis, where selective deprotection is required to build complex peptide sequences. Its application is crucial in the production of pharmaceuticals, bioactive peptides, and research involving protein engineering.
