Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 479.52 g/mol gives 3-Oxo Rosuvastatin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Oxo Rosuvastatin (CAS 1346747-49-6) is a high-purity analytical reference standard with the molecular formula C22H26FN3O6S and a molecular weight of 479.52 g/mol.
3-Oxo Rosuvastatin (C22H26FN3O6S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-Oxo Rosuvastatin under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
