Description
As a certified reference material (CRM), Ethacridine Lactate 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 Ethacridine Lactate Impurity 12 (CAS 20304-69-2), a pharmacopoeial impurity reference standard (molecular formula C15H11ClN2O3, MW 302.71 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C15H11ClN2O3, Ethacridine Lactate Impurity 12 contains a nitrogen-containing heterocyclic scaffold, 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 302.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
