Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 570.03 g/mol gives Amlodipine Besilate EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Amlodipine Besilate EP Impurity B (CAS CATO-C4X-109562) is a certified pharmaceutical impurity reference standard with the molecular formula C29H32ClN3O7 and a molecular weight of 570.03 g/mol.
Based on its molecular formula C29H32ClN3O7, Amlodipine Besilate EP Impurity B contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 570.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Amlodipine Besilate EP Impurity B 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.
