DL-LYSINE:2HCL (1-13C; EPSILON-15N) is a labeled, free amino acid salt consisting of DL-lysine in the form of a dihydrochloride, bearing an aliphatic side chain with a terminal ε-amino group and a backbone containing an α-amino and α-carboxyl functional group. The molecule includes isotopic enrichment with 1-13C at the carbonyl carbon (α-carboxyl carbon) and 15N at the ε-position nitrogen, and the presence of two hydrochloride counterions is associated with protonation of the amino functionalities. As an isotopically labeled lysine salt, it is used in peptide and protein labeling workflows, NMR and mass spectrometric method development, and structure-analysis or isotopic-tracing studies where defined incorporation of lysine-derived signals is required.
