S-Methyl-L-thiocitrulline is a sulfur-containing, non-proteinogenic amino acid derivative related to thiocitrulline, featuring a modified thiourea/thiocarbamoyl framework with an S-methyl substituent and an amino acid backbone consistent with an amino acid class building block. The molecule bears an amino functional group and a carboxyl group, and its side-chain functionality is defined by the thioamide-like sulfur that is methylated at the S-position, with the name indicating an L stereochemical configuration at the amino acid center. S-Methyl-L-thiocitrulline is used as a substrate or structural probe in chemical biology and peptide/urea-derivative synthesis workflows where thiourea-related reactivity, sulfur substitution patterns, and stereodefined amino acid scaffolds are required for preparing labeled or structurally modified analogues.
