This compound is primarily used in peptide synthesis as a protecting group for amino acids. The Boc (tert-butyloxycarbonyl) group safeguards the amino group during the synthesis process, while the Bzl (benzyl) group protects the hydroxyl group. It is particularly useful in solid-phase peptide synthesis (SPPS) to ensure selective reactions and prevent unwanted side reactions. After the peptide chain is assembled, the Boc and Bzl groups can be removed under specific conditions, allowing for the final peptide product to be obtained. Its application is crucial in producing peptides with high purity and precise sequences, which are essential in pharmaceutical research and drug development.
