Chemical Structure

Atorvastatin Impurity N5 CAS 1403667-07-1 chemical structure

Description

The occurrence of Atorvastatin Impurity N5 is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Atorvastatin Impurity N5 (CAS 1403667-07-1), a pharmacopoeial impurity reference standard (molecular formula C14H9Cl2FO, MW 283.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H9Cl2FO, Atorvastatin Impurity N5 contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.13 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.

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 Impurity N5 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.
