L-ASPARAGINE:H2O (13C4) is an isotopically labeled form of the amino acid asparagine, containing a side chain with a terminal amide and a primary α-amino group and α-carboxyl group, with four carbon atoms enriched in 13C and associated with water as a hydrate. The molecule is presented as the L stereochemical form, and the carboxyl functionality and amide side chain provide hydrogen-bonding and polarity that can be tracked by carbon-13 NMR or mass spectrometry, while the water of hydration influences its solid-state form and handling behavior. As an isotopologue, it is used in amino acid profiling, isotopic tracing, and analytical method development for studying incorporation, turnover, or labeling patterns in peptide and protein-related workflows where carbon-13 enrichment is monitored.
