L-METHIONINE (1-13C; 15N) is an isotopically labeled proteinogenic amino acid of the methionine family, featuring a thioether-containing side chain attached to the α-carbon along with an amino group and a carboxyl group. The molecule bears the stable isotope labels 13C at the specified carbon position and 15N on the amino nitrogen, preserving the native methionine connectivity and stereochemical form indicated by the L designation. As a labeled methionine analogue, it is used in isotopic tracing, NMR or mass spectrometric method development, and peptide or protein labeling workflows where incorporation of a methionine residue bearing defined 13C/15N enrichment is required for analytical readout.
