Chemical Structure
Description
The occurrence of Atorvastatin Cyclic (Fluorophenyl) 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) Calcium Salt (CAS CATO-C4X-113243), molecular formula C33H34FN2O7Ca and molecular weight 629.72 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Atorvastatin Cyclic (Fluorophenyl) Calcium Salt (C33H34FN2O7Ca) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.5, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 629.72 g/mol, it falls into the high-molecular-weight range. 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).
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.
As a certified reference material (CRM), Atorvastatin Cyclic (Fluorophenyl) 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.
