DL-ALANINE (3-13C; 2-D) is a stable isotope-labeled alanine derivative in which the amino acid framework bears a 13C label at the C-3 position and deuterium at the 2-position, corresponding to a DL (racemic) mixture of stereoisomers. The molecule contains both an amino group and a carboxyl group on the alpha carbon, with a methyl side chain that confers the characteristic alanine hydrophobicity and supports incorporation into peptides through standard amino acid coupling chemistry. Labeled alanine is used in isotopic tracing, NMR or mass spectrometric method development, and quantitative studies where controlled labeling at specific carbon and hydrogen positions is required for monitoring alanine-derived fragments in chemical and biochemical workflows.
