Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 442.29 g/mol gives Clevidipine Impurity 39 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Clevidipine Impurity 39 (CAS CATO-C4X-101539) is a certified pharmaceutical impurity reference standard with the molecular formula C20H21Cl2NO6 and a molecular weight of 442.29 g/mol.
Based on its molecular formula C20H21Cl2NO6, Clevidipine Impurity 39 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 442.29 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
