L-METHIONINE (D8; 15N) is an isotopically labeled, naturally occurring amino acid in the thioether-bearing methionine class, retaining the methionine backbone with a side chain that contains a sulfur atom. The molecule carries eight deuterium atoms and one 15N label within the amino acid framework (including the amino nitrogen), providing a distinct isotopic signature while maintaining the free amino and carboxyl functional groups. L-METHIONINE (D8; 15N) is used as a stable-isotope tracer and analytical standard for labeling, mass spectrometry-based quantification, and incorporation studies in peptide and protein sample preparation workflows where isotopic discrimination is required.
