The occurrence of Pravastatin EP Impurity C Sodium Salt is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pravastatin EP Impurity C Sodium Salt (CAS 159225-12-4) is a certified pharmaceutical impurity reference standard with the molecular formula C24H37O7Na and a molecular weight of 460.54 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Pravastatin EP Impurity C Sodium Salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 460.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Pravastatin 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.
