D-ALANINE (2,3-13C2) is the D-enantiomer of alanine in which the carbon atoms at positions 2 and 3 are isotopically labeled with 13C, retaining the amino acid backbone classification and methyl side chain characteristic of alanine. The molecule contains a free primary amino group and a free carboxyl group, with the side chain bearing a hydrophobic methyl substituent that differentiates its chemical reactivity from amino acids with polar or charged side chains. As an isotopically labeled amino acid, it is used in isotopic tracing, NMR or mass spectrometric method development, and peptide or protein labeling workflows where incorporation of a defined 13C pattern into downstream analytes is required for structural or kinetic studies.
