Rosuvastatin Impurity N1 CAS 849470-61-7

Description

Compared with other compounds in its class, the molecular weight of 322.35 g/mol gives Rosuvastatin Impurity N1 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Rosuvastatin Impurity N1 (CAS 849470-61-7) is a certified pharmaceutical impurity reference standard with the molecular formula C15H15FN2O3S and a molecular weight of 322.35 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Rosuvastatin Impurity N1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.35 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.

CATO manufactures Rosuvastatin Impurity N1 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
