This chemical is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a protected glutamine derivative, where the Z group (benzyloxycarbonyl) protects the amine, and the Trt group (trityl) protects the side chain amide. This protection strategy ensures selective reactions during peptide chain assembly, preventing unwanted side reactions. It is especially useful in synthesizing complex peptides and proteins for research in biochemistry, pharmaceuticals, and biotechnology. Additionally, it is employed in the production of peptide-based drugs, vaccines, and diagnostic reagents, where precise control over amino acid incorporation is critical.
