Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Atorvastatin Epoxy Pyrrolooxazin Tricyclic Calcium Salt (CAS CATO-C4X-1132109), molecular formula C33H32FN2O6Ca and molecular weight 611.70 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C33H32FN2O6Ca, Atorvastatin Epoxy Pyrrolooxazin Tricyclic 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 611.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Atorvastatin Epoxy Pyrrolooxazin Tricyclic 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.
