Verapamil Impurity N2 CAS 3017-96-7 chemical structure

Description

CATO supplies Verapamil Impurity N2 (CAS 3017-96-7), a pharmacopoeial impurity reference standard (molecular formula C3H6BrCl, MW 157.44 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C3H6BrCl, Verapamil Impurity N2 contains chlorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 157.44 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.

As a certified reference material (CRM), Verapamil Impurity N2 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.
