L-ASPARTIC ACID (1,4-13C2) is a stable-isotope-labeled, proteinogenic amino acid featuring the aspartate side chain with a terminal carboxylic acid and an amino acid backbone bearing an α-amino and α-carboxyl group. The molecule is specified as the L-stereoisomer and contains two 13C atoms at the 1 and 4 positions, enabling carbon-site-resolved tracing while retaining the native acidic side-chain functionality that can form salt or engage in hydrogen-bonding and ionic interactions. L-ASPARTIC ACID (1,4-13C2) is used in isotopic labeling for amino-acid and peptide analysis by mass spectrometry and NMR, supporting studies that track incorporation, scrambling, or relative contributions of aspartate-derived carbon atoms in chemically defined systems.
