Description
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.
Lifitegrast Impurity 126 (CAS CATO-C4X-2409126) is a certified pharmaceutical impurity reference standard with the molecular formula C49H42Cl4N4O11S2 and a molecular weight of 1068.82 g/mol.
Based on its molecular formula C49H42Cl4N4O11S2, Lifitegrast Impurity 126 contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1068.82 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.
As a certified reference material (CRM), Lifitegrast Impurity 126 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.
