L-ORNITHINE:HCL (5,5-D2) is a deuterium-labeled amino acid salt in which L-ornithine is present as the hydrochloride, with deuterium incorporated at the side-chain carbon positions indicated as 5,5-D2. The molecule contains a primary amino group and a carboxyl functional group characteristic of amino acids, while the side chain bears an additional amino functionality that can be protonated and participates in ionic interactions, and the D2 labeling provides an isotopic handle for mass-based detection. As an isotopically labeled ornithine derivative, it is used in isotopic tracing, quantitative LC-MS or GC-MS analytical method development, and chemical biology studies that require tracking of ornithine-derived fragments or monitoring of transformations involving the labeled carbon framework.
CAT No: L-Iso-0466
