Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 412.31 g/mol gives Clevidipine Impurity 36 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Clevidipine Impurity 36 (CAS CATO-C4X-101536) is a certified pharmaceutical impurity reference standard with the molecular formula C20H23Cl2NO4 and a molecular weight of 412.31 g/mol.
Structurally, Clevidipine Impurity 36 (C20H23Cl2NO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 412.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Clevidipine Impurity 36 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.
