Chemical Structure

Atorvastatin Cyclic Fluorophenyl Impurity(Calcium Salt) CAS CATO-C4X-113281 chemical structure

Description

The occurrence of Atorvastatin Cyclic Fluorophenyl Impurity(Calcium Salt) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Atorvastatin Cyclic Fluorophenyl Impurity(Calcium Salt) (CAS CATO-C4X-113281) is a certified pharmaceutical impurity reference standard with the molecular formula C33H34FN2O7Ca and a molecular weight of 629.72 g/mol.

Based on its molecular formula C33H34FN2O7Ca, Atorvastatin Cyclic Fluorophenyl Impurity(Calcium Salt) contains a nitrogen-containing heterocyclic scaffold, 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 629.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), Atorvastatin Cyclic Fluorophenyl Impurity(Calcium Salt) 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.
