Description
CATO supplies Stiripentol Impurity 6 (CAS CATO-C4X-32296), a pharmacopoeial impurity reference standard (molecular formula C14H17ClO2, MW 252.74 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C14H17ClO2, Stiripentol Impurity 6 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.74 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.
