Chemical structure of Fmoc-L-cysteic acid · disodium salt

GA21706

Fmoc-L-cysteic acid · disodium salt

Also known as disodium;(2R)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-sulfonatopropanoate

Protected derivative for the introduction of this highly polar amino acid· Cya-containing peptides are obtained by oxidation of cysteine or cystine, as a post-translational modification, as a by-product during peptide synthesis, or, intentionally (by using oxidants as H?O?/formic acid), for quantification of these sensitive amino acids· Use of B-4030 allows to obtain Cya-peptides containing sensitive amino acids, as an additional oxidation step is not required
