(S)-2-((tert-Butoxycarbonyl)amino)-5-(3-tosylguanidino)pentanoic acid（Cat No.:M062276）is a specialized amino acid derivative used in peptide synthesis. The tert-butoxycarbonyl (Boc) group on the amino group protects it from undesired reactions, ensuring controlled incorporation into peptide sequences. The 3-tosylguanidino group at the side chain enhances the molecule’s basicity and provides opportunities for specific ionic interactions, making it useful for designing peptides with targeted bioactivity. After peptide synthesis, the Boc group can be removed under mild acidic conditions to reveal the free amino group, enabling further modifications and elongation in peptide synthesis.
