Chemical Structure

Felodipine EP Impurity A CAS 96382-71-7 chemical structure

Description

The occurrence of Felodipine EP Impurity A is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Felodipine EP Impurity A (CAS 96382-71-7) is a certified pharmaceutical impurity reference standard with the molecular formula C18H17Cl2NO4 and a molecular weight of 382.24 g/mol.

Based on its molecular formula C18H17Cl2NO4, Felodipine EP Impurity A contains a flavonoid core, 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 382.24 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 Felodipine EP Impurity A 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.
