Chemical Structure
Description
The occurrence of Mexiletine Impurity 14 is closely related to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Mexiletine Impurity 14 (CAS CATO-C4X-192914), a pharmacopoeial impurity reference standard (molecular formula C18H22O4S, MW 334.43 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C18H22O4S, Mexiletine Impurity 14 contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 334.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Impurity 14 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.
