Structurally, Osimertinib Impurity 22 (C56H66N14O4HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 30.0, corresponding to approximately 30 ring(s) or double-bond equivalent(s). With a molecular weight of 1035.70 g/mol, it falls into the 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).
Osimertinib Impurity 22 (CAS CATO-C4X-204522) is a certified pharmaceutical impurity reference standard with the molecular formula C56H66N14O4HCl and a molecular weight of 1035.70 g/mol.
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.
