Used primarily in peptide synthesis as a building block to incorporate serine residues into peptide chains. Its tert-butyl protection group ensures stability during the synthesis process, preventing unwanted side reactions. The methyl ester group enhances solubility in organic solvents, making it suitable for solid-phase peptide synthesis. It is particularly valuable in the production of complex peptides for pharmaceutical research and drug development, where precise control over amino acid incorporation is critical. Additionally, it aids in the study of peptide structure and function, contributing to advancements in biochemistry and medicinal chemistry.
