Description
As a certified reference material (CRM), Clopidogrel benzenesulfonate 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.
Clopidogrel benzenesulfonate (CAS 744256-69-7) is a high-purity analytical reference standard with the molecular formula C16H16ClNO2SC6H6O3S and a molecular weight of 479.99 g/mol.
Based on its molecular formula C16H16ClNO2SC6H6O3S, Clopidogrel benzenesulfonate contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 479.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
