Description
Mavacoxib Impurity 6 (CAS 170569-97-8) is a certified pharmaceutical impurity reference standard with the molecular formula C16H11F4N3O2S and a molecular weight of 385.34 g/mol.
Based on its molecular formula C16H11F4N3O2S, Mavacoxib Impurity 6 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 385.34 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), Mavacoxib Impurity 6 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.
