This compound is widely used in peptide synthesis as a protecting group for tryptophan. The Boc (tert-butyloxycarbonyl) group safeguards the amino group, while the OBzl (benzyl ester) protects the carboxyl group, allowing selective reactions during peptide chain assembly. It is particularly valuable in solid-phase peptide synthesis (SPPS) to prevent unwanted side reactions. Additionally, it is employed in the preparation of complex peptides and proteins for research in biochemistry and pharmaceuticals. Its stability under various reaction conditions makes it a preferred choice for synthesizing peptides with high purity and yield.
