Chemical Structure
Description
Owing to a nitrile group, chlorine substitution, Mianserin Impurity 67 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Mianserin Impurity 67 (CAS CATO-C4X-136967) is a certified pharmaceutical impurity reference standard with the molecular formula C10H13Cl2NHCl and a molecular weight of 254.58 g/mol.
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.
