L-ASPARTIC ACID (4-13C) is an isotopically labeled proteinogenic amino acid belonging to the acidic amino acid class, featuring a side chain with a terminal carboxylic acid and a backbone containing both an amino group and a carboxyl group. The molecule is specified as the L stereoisomer and bears a 13C label at the 4-position of the aspartate side chain, enabling it to act as an isotopic tracer while maintaining the native-like functional group pattern of aspartic acid. L-ASPARTIC ACID (4-13C) is used in isotopic labeling and analytical method development for tracking incorporation, studying amino acid transformations by mass spectrometry or related techniques, and supporting the preparation of labeled peptide or amino acid derivatives where the labeled carbon position is retained.
CAT No: L-Iso-0137
