Used primarily in peptide synthesis, this compound serves as a protected amino acid derivative. It is particularly valuable in the construction of complex peptides, where it helps to prevent unwanted side reactions during the coupling process. The tert-butyl ester group provides stability under acidic conditions, making it suitable for use in solid-phase peptide synthesis (SPPS). Additionally, its N-methylation enhances resistance to enzymatic degradation, which is beneficial in the development of peptide-based pharmaceuticals. This chemical is also employed in the preparation of peptide libraries for drug discovery and biochemical research, enabling the exploration of new therapeutic targets.
