This chemical is primarily used in peptide synthesis as a protected form of lysine. The benzyloxycarbonyl (Z) group protects the amino group of lysine, preventing unwanted reactions during the peptide chain assembly. It is particularly valuable in solid-phase peptide synthesis (SPPS) and solution-phase synthesis, where selective deprotection is required to build complex peptides. Its application extends to the production of bioactive peptides, pharmaceuticals, and research compounds, where precise control over amino acid incorporation is essential. Additionally, it serves as a building block in the development of peptide-based drugs, vaccines, and diagnostic agents, contributing to advancements in medicinal chemistry and biotechnology.
