DL-GLUTAMIC ACID (5-13C) is a stable-isotope-labeled amino acid belonging to the acidic, proteinogenic glutamate family, featuring a side chain with a terminal carboxyl group attached to the α-amino acid backbone. The molecule contains an amino group and a carboxyl group on the α-carbon as well as a second carboxyl group on the glutamate side chain, and it is provided as the DL stereochemical mixture with 13C enrichment at the carbon positions indicated by "(5-13C)". As an isotopically labeled glutamic acid analogue, it is used in isotopic tracing, quantitative mass spectrometry and NMR method development, and peptide or biomolecule synthesis workflows where incorporation of a 13C-labeled acidic residue is required for structural analysis or labeling studies.
