L-HISTIDINE:HCL:H2O (<5% D) (13C6) is a stereochemically defined, isotopically labeled amino acid salt in which histidine is present as its hydrochloride hydrate form, with six ring carbons labeled as 13C. The molecule contains an imidazole side chain capable of acid-base behavior, along with a free amino group and a carboxyl group associated with the histidine scaffold, while the stated <5% D indicates a small fraction of the D stereoisomer. This labeled histidine hydrochloride hydrate is used in isotopic tracing, NMR/IR or mass spectrometric method development, and quantitative studies that require incorporation of a 13C6-labeled imidazole-containing amino acid into analytical standards or peptide- and protein-related chemical probes.
