This compound is primarily utilized in peptide synthesis as a protected amino acid derivative. It serves as a key intermediate in the production of peptides, where the tert-butoxycarbonyl (Boc) group protects the amino group during the synthesis process, preventing unwanted reactions. The tert-butyl ester moiety also acts as a protective group for the carboxyl group, ensuring selective reactions at other sites. Its application is crucial in the development of pharmaceuticals, particularly in the synthesis of peptide-based drugs, where precise control over amino acid reactivity is essential. Additionally, it is used in research settings for studying peptide structures and functions, aiding in the design of novel therapeutic agents.
