Atorvastatin Impurity 124 CAS 666714-64-3

Description

Compared with other compounds in its class, the molecular weight of 398.47 g/mol gives Atorvastatin Impurity 124 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Atorvastatin Impurity 124 (CAS 666714-64-3), a pharmacopoeial impurity reference standard (molecular formula C26H23FN2O, MW 398.47 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C26H23FN2O, Atorvastatin Impurity 124 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 398.47 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.

CATO manufactures Atorvastatin Impurity 124 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.
