This compound is primarily utilized in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing specific peptide sequences, particularly where the incorporation of lysine or its derivatives is required. The benzyloxycarbonyl (Cbz) protecting groups ensure that the amino functionalities remain intact during the synthesis process, preventing unwanted side reactions. After the peptide chain is assembled, the Cbz groups can be selectively removed under mild conditions, allowing for further modifications or the final deprotection of the peptide. Its application is crucial in pharmaceutical research and development, especially in the design of peptide-based drugs and biomaterials.
