L-HISTIDINE:HCL:H2O (<5% D) (RING-2-13C) is a hydrochloride monohydrate salt of the amino acid L-histidine, featuring an imidazole side chain that can participate in acid-base chemistry and coordination. The molecule contains an amino group and a carboxyl group on the histidine backbone, while the imidazole ring bears a 13C label at the 2-position, and the stated composition indicates less than 5% deuterium (D) in the material. As an isotopically labeled amino acid salt, it is used for isotopic tracing, NMR or mass spectrometric analytical method development, and quantitative studies of amino-acid incorporation or transformation in peptide and protein chemistry workflows.
CAT No: L-Iso-0310
