Chemical Structure
Description
L-Arginine-13C6,15N4 hydrochloride (CAS 202468-25-5) is a high-purity analytical reference standard with the molecular formula [13C]6H14[15N]4O2 HCl and a molecular weight of 108.59 g/mol.
The molecular framework of L-Arginine-13C6,15N4 hydrochloride ([13C]6H14[15N]4O2 HCl) is characterized by chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), L-Arginine-13C6,15N4 hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
