Used primarily in peptide synthesis, it serves as a protected form of lysine, ensuring selective reactions during the formation of peptide bonds. The benzyloxycarbonyl (Z) group protects the amino group, while the benzyl ester safeguards the carboxyl group, allowing for controlled deprotection steps. This compound is particularly valuable in creating complex peptides for research in biochemistry and pharmaceuticals, aiding in the development of therapeutic agents and bioactive peptides. Its stability and ease of handling make it a preferred choice in solid-phase peptide synthesis and other advanced organic synthesis techniques.
