S-Allyl-DL-cysteine Sulfoxide is a sulfur-containing amino acid derivative in which the cysteine backbone bears an S-allyl thioether and a sulfoxide oxidation state at the sulfur atom, with the amino acid framework present as a free amino acid motif and a carboxyl group. The molecule is specified as DL, indicating a racemic mixture at the cysteine stereocenter, and the sulfoxide functionality provides a polar, oxidized sulfur center while the allyl substituent maintains a neutral, hydrophobic side-chain handle for chemical modification. In research settings, this compound is used as a chemically defined cysteine sulfoxide analogue for peptide and thioether/sulfoxide structure-activity studies, for preparing further sulfur-oxidation-state variants, and as a substrate-like building block in synthesis and analytical method development targeting sulfoxide-bearing amino acid motifs.
