L-ALANINE (2-13C; 15N) is an isotopically labeled form of the proteinogenic amino acid alanine, featuring a methyl side chain attached to a chiral α-carbon bearing an amino group and a carboxyl group. The molecule contains a 13C label at the carbon-2 position and a 15N label on the amino functionality, while retaining the standard alanine connectivity and stereochemistry implied by the L designation. As an isotopic tracer, this labeled amino acid is used in NMR, MS-based metabolite and amino acid profiling, and peptide or protein labeling workflows where incorporation of the labeled nitrogen and carbon enables tracking of nitrogen transfer and carbon-containing fragments in analytical studies.
