L-ARGININE:HCL (D7) is an isotopically labeled amino acid salt in which L-arginine is present as the hydrochloride, with deuterium incorporation indicated by "(D7)". The molecule contains the amino acid α-amino and α-carboxyl functional groups and features an arginine side chain bearing a guanidinium group that is protonated under acidic conditions, while the hydrochloride counterion balances charge and supports salt formation. In research and analytical workflows, the deuterium labeling enables isotopic tracing and mass spectrometric quantification of arginine-related species, and the free amino acid salt form serves as a defined precursor for chemical derivatization and peptide or conjugate synthesis where arginine residues are required.
CAT No: L-Iso-0092
