Chemical Structure
Description
The molecular framework of 5-Oxo Atorvastatin Calcium salt (C33H32FN2O5Ca) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5-Oxo Atorvastatin Calcium salt (CAS CATO-C4X-113245) is a high-purity analytical reference standard with the molecular formula C33H32FN2O5Ca and a molecular weight of 595.70 g/mol.
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 5-Oxo Atorvastatin Calcium salt 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.
