S-Allyl-D-cysteine is a sulfur-modified cysteine derivative featuring a D-cysteine backbone with the thiol side chain converted to an S-allyl thioether. The molecule contains both an amino group and a carboxyl group on the α-carbon, while the allyl substituent replaces the free thiol functionality, changing the side-chain from a reducible thiol to a thioether-bearing allyl moiety. In peptide and chemical biology workflows, S-allyl-D-cysteine is used as a chemically defined cysteine analogue for introducing an allyl-functional sulfur side chain into synthetic sequences or for preparing further sulfur-linked conjugates and labeled or crosslinkable amino acid derivatives.
