L-LYSINE:2HCL (6-13C) is an isotopically labeled form of the amino acid L-lysine, supplied as a dihydrochloride salt, in which six carbon atoms are enriched with 13C. The molecule contains the free amino group(s) and carboxyl group characteristic of lysine, while the side chain terminates in a primary ε-amino functionality that is protonated under the salt conditions, and the labeled carbon framework is distributed across the lysine carbon skeleton as indicated by the (6-13C) designation. As an isotopically enriched amino acid salt, it is used in peptide and protein labeling workflows, mass spectrometry-based analytical method development, and chemical biology studies requiring carbon-tracing or isotopic discrimination during synthesis and characterization of amino acid and peptide derivatives.
