L-ALANINE (1-13C) is an isotopically labeled form of the proteinogenic amino acid alanine, featuring a methyl side chain attached to the α-carbon and a stereochemically defined amino acid backbone consistent with the L-alanine family. The molecule contains a free amino group and a carboxyl group on the α-carbon, with the side-chain methyl carbon bearing the 13C label at the position indicated in the product name. As an isotopically labeled amino acid, it is used in isotopic tracing, NMR/IR mass spectrometric method development, and peptide or protein labeling workflows where incorporation of a defined 13C site supports quantitative tracking of alanine-derived fragments.
