Chemical Structure
Description
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
Bevantolol Impurity 20 (CAS CATO-C4X-241120) is a certified pharmaceutical impurity reference standard with the molecular formula C19H25NO4HCl and a molecular weight of 367.87 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Bevantolol Impurity 20 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 367.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Bevantolol Impurity 20 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.
