L-ASPARTIC ACID (2,3,3-D3; 15N) is an isotopically labeled, proteinogenic amino acid of the aspartic acid family featuring a side-chain carboxylic acid and a primary amino group attached to the alpha carbon. The molecule bears an alpha-carboxyl group and an additional side-chain carboxyl group, with deuterium incorporation at positions 2 and 3 (3,3-D3) and a 15N label on the amino nitrogen, while retaining the L stereochemical designation stated in the product name. This labeled aspartic acid is used in isotopic tracing, quantitative mass spectrometry and NMR method development, and peptide or protein labeling workflows where defined incorporation of a heavy-atom isotopic marker is required for structural analysis or analytical discrimination.
