Chemical Structure
Description
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.
Arbidol Impurity 30 (CAS CATO-C4X-112930) is a certified pharmaceutical impurity reference standard with the molecular formula C22H24BrNO4S and a molecular weight of 478.40 g/mol.
Based on its molecular formula C22H24BrNO4S, Arbidol Impurity 30 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 478.40 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.
