The occurrence of Rosuvastatin Impurity 132 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Rosuvastatin Impurity 132 (CAS 2626928-14-9) is a certified pharmaceutical impurity reference standard with the molecular formula C21H24FN3O6SNa and a molecular weight of 488.49 g/mol.
Based on its molecular formula C21H24FN3O6SNa, Rosuvastatin Impurity 132 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 488.49 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.
As a certified reference material (CRM), Rosuvastatin Impurity 132 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.
