L-METHIONINE (METHYL-13C; METHYL-D3) is an isotopically labeled proteinogenic amino acid of the thioether-bearing methionine class, featuring an amino group and a carboxyl group on the α-carbon and a side chain with a sulfide-linked methyl group. The molecule bears a methyl group enriched with 13C and three deuterium atoms (D3) on that same side-chain methyl, while retaining the stereochemical form indicated by the "L-" designation. As an isotopically labeled methionine analogue, it is used in peptide and protein labeling workflows, isotopic tracing, and mass spectrometry-based analytical method development where the labeled thioether methyl provides a chemically specific marker for structural studies and quantitation.
