This compound is primarily utilized in peptide synthesis, where it serves as a protected form of D-asparagine. The carbobenzoxy (Cbz) group acts as a protecting group for the amino functionality, preventing unwanted reactions during the synthesis process. This is particularly important in solid-phase peptide synthesis (SPPS) and solution-phase peptide synthesis, where selective deprotection and coupling steps are critical. Its application ensures the precise assembly of peptide chains, especially in the synthesis of complex peptides or proteins that require specific stereochemistry. Additionally, it is used in research and development for creating peptide-based drugs, where the D-asparagine residue plays a role in the biological activity or stability of the final product.
