L-ASPARTIC ACID (13C4,D3,15N) is an isotopically labeled form of the proteinogenic amino acid aspartic acid, bearing a side-chain carboxylic acid (-CH2-COOH) characteristic of the Asp class. The molecule contains an amino group and a carboxyl group at the α-position, with the labeling indicated by four 13C atoms, three deuterium atoms (D3), and one 15N atom (15N) distributed across the amino acid framework while retaining the L stereochemical designation. As an isotopically enriched amino acid, it is used in peptide and protein labeling workflows, isotopic tracing, and quantitative analytical method development where mass-dependent detection of incorporation or chemical transformation is required.
CAT No: L-Iso-0120
