Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 522.57 g/mol gives Ticagrelor Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ticagrelor Impurity 3 (CAS 2096989-56-7) is a certified pharmaceutical impurity reference standard with the molecular formula C23H28F2N6O4S and a molecular weight of 522.57 g/mol.
Structurally, Ticagrelor Impurity 3 (C23H28F2N6O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 522.57 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 3 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.
