Chemical Structure

Atorvastatin EP Impurity M CAS 1146977-93-6 chemical structure

Description

The molecular framework of Atorvastatin EP Impurity M (C35H39FN2O5) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Atorvastatin EP Impurity M (CAS 1146977-93-6) is a certified pharmaceutical impurity reference standard with the molecular formula C35H39FN2O5 and a molecular weight of 586.69 g/mol.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

CATO manufactures Atorvastatin EP Impurity M 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.
