(S)-Methyl 2-((tert-butoxycarbonyl)amino)-3-methylbutanoate（Cat No.:R030999）is a protected amino acid derivative used in peptide synthesis. It features a tert-butoxycarbonyl (Boc) group on the amino group, which shields it from unwanted reactions during synthesis, ensuring selective incorporation into peptide chains. The methyl ester at the carboxyl group enhances its solubility and reactivity, facilitating coupling reactions. This compound is particularly useful for incorporating the (S)-enantiomer of the amino acid into peptides, commonly employed in pharmaceutical research and drug development. The Boc group can be easily removed under mild acidic conditions to expose the free amino group.
