Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 589.57 g/mol gives Ezetimibe Impurity 41 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ezetimibe Impurity 41 (CAS CATO-C4X-109841) is a certified pharmaceutical impurity reference standard with the molecular formula C30H25D4F2NO9 and a molecular weight of 589.57 g/mol.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Ezetimibe Impurity 41 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 589.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Ezetimibe Impurity 41 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.
