L-ORNITHINE:HCL (ALPHA-15N) is a free amino acid salt in which L-ornithine is present as the hydrochloride, with the amino acid nitrogen labeled by 15N at the alpha position. The molecule contains both an alpha-amino group and a carboxyl group, and its side chain is a primary amine (-(CH2)3-NH2) that can engage in protonation/deprotonation equilibria, while the HCl counterion forms the corresponding salt to control ionic form. As an isotopically labeled ornithine analogue, it is used in isotopic tracing, NMR or mass spectrometric method development, and quantitative studies of nitrogen-containing metabolites or peptide-related intermediates where alpha-nitrogen labeling is required.
CAT No: L-Iso-0470
