L-ARGININE:HCL (13C6,D7,15N4) is an isotopically labeled form of the amino acid arginine supplied as its hydrochloride salt, featuring a guanidinium-containing side chain attached to the α-amino and α-carboxyl groups of the amino acid backbone. The molecule bears the guanidinium functionality characteristic of arginine, and the label set (13C6, D7, 15N4) replaces the corresponding atoms within the arginine framework while the hydrochloride counterion associates with the basic groups to form the salt. As a stable isotope-enriched arginine derivative, it is used in isotopic tracing, quantitative mass spectrometry-based analytical workflows, and synthesis or labeling strategies for peptide and protein studies where incorporation of a defined, heavy-atom isotopic signature is required.
