L-METHIONINE (METHYL-13C) is an isotopically labeled, proteinogenic amino acid belonging to the thioether-containing amino acid family, featuring the methionine side chain with a methyl group labeled by 13C. The molecule contains both an amino group and a carboxyl group in the free amino acid form, with the thioether sulfur bearing the labeled methyl substituent while maintaining the amino acid backbone stereochemistry associated with the L-methionine designation. L-METHIONINE (METHYL-13C) is used in isotopic tracing, mass spectrometry and NMR-based analytical method development, and peptide or protein labeling workflows where incorporation of the labeled methionine side-chain carbon is monitored.
