Fmoc-L-Cysteine(Acm)-OH (Fmoc-Cys(Acm)-OH) is an
Fmoc-protected amino acid building block for Fmoc/tBu solid-phase peptide
synthesis (SPPS). Also known as N-Fmoc-S-acetamidomethyl-L-cysteine. Acm
survives TFA cleavage, which allows regioselective disulfide-bond formation in
multi-cysteine peptides. As ApiSyn also manufactures peptide APIs,
building-block supply can be matched to your peptide scale-up.
