L-LYSINE:2HCL (1-13C; ALPHA-15N) is a labeled, salt-form derivative of the naturally occurring basic amino acid lysine, bearing an ε-amine side chain and a free α-amino and α-carboxyl framework in the form of a dihydrochloride. The molecule contains isotopic labels at the α-amino nitrogen (15N) and at the α-carbon (1-13C), with the hydrochloride counterions associated to the amino functionalities, while the stereochemistry is specified as L for the α-center. In research and analytical workflows, this isotopically labeled lysine is used as a substrate or reference material for isotopic tracing, peptide/protein labeling studies, and NMR or mass spectrometric method development where incorporation or detection of the α-13C/α-15N signature is required.
