Description
Mexiletine EP Impurity C DiHCl (CAS 2059988-39-3) is a certified pharmaceutical impurity reference standard with the molecular formula C22H32N2O2HCl and a molecular weight of 392.97 g/mol.
Based on its molecular formula C22H32N2O2HCl, Mexiletine EP Impurity C DiHCl contains a steroid 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 392.97 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Mexiletine EP Impurity C DiHCl 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.
