DL-ORNITHINE:HCL (ALPHA-15N) is a hydrochloride salt of DL-ornithine in which the alpha-amino position is isotopically labeled with 15N, classifying it as a basic, non-proteinogenic amino acid derivative used for isotopic tracing and analytical studies. The molecule contains a free carboxyl group and a primary amino group on the alpha carbon, with an additional side-chain primary amine on the ornithine backbone that can undergo acid-base interactions, while the hydrochloride counterion balances the basic functionality. As an isotopically labeled amino acid salt, it is employed in amino acid metabolism and transamination studies, peptide and protein labeling workflows, and mass spectrometry or NMR method development where incorporation of the 15N label into downstream analytes is monitored.
