L-ASPARTIC ACID (2,3,3-D3) is an isotopically labeled, proteinogenic amino acid belonging to the acidic amino acid family, featuring the standard α-amino and α-carboxyl functional groups and a side chain that terminates in a carboxylic acid. The molecule bears deuterium substitution at the 2,3,3 positions of the aspartate carbon framework while retaining the L stereochemical form indicated by the product name, and the side-chain carboxyl group can participate in acid-base equilibria relevant to peptide and buffer chemistry. L-ASPARTIC ACID (2,3,3-D3) is used as a stable isotope tracer and analytical standard in isotopic labeling, amino acid quantification, and mass spectrometry-based studies that require discrimination of aspartate-derived signals.
CAT No: L-Iso-0125
