L-ASPARTIC ACID (1,4-13C2; 15N) is an isotopically labeled, naturally occurring amino acid in the aspartate family, featuring a side chain with a terminal carboxylic acid and a backbone containing both an amino group and a carboxyl group. The molecule bears the L stereochemical configuration as indicated by the name, and the labeling pattern incorporates 13C at positions 1 and 4 of the carbon framework together with 15N in the amino group, enabling mass-dependent tracking of the intact amino acid in analytical workflows. L-ASPARTIC ACID (1,4-13C2; 15N) is used as a chemically defined substrate or reference material for isotopic tracing, quantitative LC-MS/GC-MS method development, and the preparation of labeled aspartate-containing peptide or amino acid derivatives for structure-function and labeling studies.
