This chemical is primarily used in peptide synthesis as a protected lysine derivative. It serves as an intermediate in the production of complex peptides and proteins, ensuring specific amino acids are not prematurely reactive during the synthesis process. The benzyloxycarbonyl (Cbz) and tert-butoxycarbonyl (Boc) groups act as protective groups, which can be selectively removed under controlled conditions to allow further chemical modifications. This compound is particularly valuable in pharmaceutical research and development, where precise peptide sequences are required for drug discovery and biological studies. Its stability and compatibility with various synthesis protocols make it a reliable choice for constructing peptides with high purity and accuracy.
