L-ALANINE (2,3,3,3-D4) is a deuterium-labeled form of the proteinogenic amino acid alanine, featuring the standard α-amino acid backbone with a methyl side chain and the amino acid stereochemistry corresponding to L-alanine. The molecule contains an α-amino group and a carboxyl group, and the side-chain methyl hydrogens are replaced by deuterium at the 2,3,3,3 positions, providing an isotopic signature while retaining the chemical functionality of alanine. It is used as an isotopically labeled substrate or internal standard in amino acid profiling, peptide and protein labeling workflows, and analytical method development where mass-dependent detection or isotopic tracing of alanine-containing species is required.
CAT No: L-Iso-0019
