S-(Acetamidomethyl)-N-(tert-butoxycarbonyl)-L-cysteine（Cat No.:M002105）is a modified form of L-cysteine, where the amino group is protected by a tert-butoxycarbonyl (Boc) group, and the thiol group is masked with an acetamidomethyl (Acm) group. This protection strategy prevents unwanted side reactions during peptide synthesis, ensuring selective incorporation of cysteine into peptide sequences. The Boc group can be removed under mild acidic conditions, while the Acm group can be cleaved to reveal the free thiol group, essential for disulfide bond formation. This compound is useful in synthesizing peptides with cysteine for various biochemical and pharmacological applications.
