Used in peptide synthesis as a protected form of glutamine, ensuring specific reactions occur without unwanted side interactions. It is particularly valuable in solid-phase peptide synthesis (SPPS) for creating complex peptides with high precision. The Boc (tert-butoxycarbonyl) group protects the amino group during synthesis, which can be removed under acidic conditions without affecting the peptide chain. This compound is essential in producing peptides for research, pharmaceuticals, and biotechnology, where controlled and selective reactions are critical. Its application extends to the development of therapeutic peptides, vaccines, and biochemical studies.
