Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 433.45 g/mol gives Fluvastatin EP Impurity A Sodium Salt（and enantiomer） distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Fluvastatin EP Impurity A Sodium Salt（and enantiomer） (CAS 93957-58-5) is a certified pharmaceutical impurity reference standard with the molecular formula C24H25FNO4Na and a molecular weight of 433.45 g/mol.
The molecular framework of Fluvastatin EP Impurity A Sodium Salt（and enantiomer） (C24H25FNO4Na) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
