As a process- or degradation-related impurity, Ticagrelor Impurity 75 (Mixture of Diastereomers) (CAS 1863036-45-6, C17H24ClN5O5S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Ticagrelor Impurity 75 (Mixture of Diastereomers) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 445.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Ticagrelor Impurity 75 (Mixture of Diastereomers) 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.
