Description
As a certified reference material (CRM), Diclofenac Impurity 43 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.
Diclofenac Impurity 43 (CAS CATO-C4X-105143) is a certified pharmaceutical impurity reference standard with the molecular formula C14H12Cl3N and a molecular weight of 300.61 g/mol.
Based on its molecular formula C14H12Cl3N, Diclofenac Impurity 43 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 300.61 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.
