Description
Felodipine Impurity 7 (CAS CATO-C4X-10947) is a certified pharmaceutical impurity reference standard with the molecular formula C19H22Cl2O6 and a molecular weight of 417.28 g/mol.
Based on its molecular formula C19H22Cl2O6, Felodipine Impurity 7 contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 417.28 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 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.
CATO manufactures Felodipine Impurity 7 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
