Chemical Structure
Description
As a certified reference material (CRM), Viloxazine Impurity 12 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.
CATO supplies Viloxazine Impurity 12 (CAS 3024393-81-2), a pharmacopoeial impurity reference standard (molecular formula C19H24O5, MW 332.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Viloxazine Impurity 12 (C19H24O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
