Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Rosuvastatin EP Impurity L Sodium Salt (Monomer).
CATO supplies Rosuvastatin EP Impurity L Sodium Salt (Monomer) (CAS 1347362-67-7), a pharmacopoeial impurity reference standard (molecular formula C22H29FN3O6SNa, MW 505.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H29FN3O6SNa, Rosuvastatin EP Impurity L Sodium Salt (Monomer) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 505.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Rosuvastatin EP Impurity L Sodium Salt (Monomer) 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.
