Chemical Structure
Description
The occurrence of Fluvastatin EP Impurity C(Sodium Salt) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Fluvastatin EP Impurity C(Sodium Salt) (CAS 2451176-31-9 (free acid)) is a certified pharmaceutical impurity reference standard with the molecular formula C23H23FNNaO4 and a molecular weight of 419.42 g/mol.
Based on its molecular formula C23H23FNNaO4, Fluvastatin EP Impurity C(Sodium Salt) contains a flavonoid core, 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 419.42 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.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Fluvastatin EP Impurity C(Sodium 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.
