This compound is primarily used in peptide synthesis as a protected amino acid derivative. It serves as a building block for constructing peptides, where the serine residue is protected by a tert-butyl group, preventing unwanted reactions during the synthesis process. The methyl ester group enhances solubility and facilitates handling in organic solvents. Its application is crucial in the development of pharmaceuticals, particularly in the production of peptide-based drugs, where precise control over amino acid incorporation is essential. Additionally, it is utilized in research to study peptide structure and function, aiding in the design of novel therapeutic agents.
