Chemical Structure
Description
The occurrence of para-Hydroxy Atorvastatin Calcium Salt is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
para-Hydroxy Atorvastatin Calcium Salt (CAS 265989-44-4), molecular formula C33H34FN2O6Ca and molecular weight 613.72 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of para-Hydroxy Atorvastatin Calcium Salt (C33H34FN2O6Ca) 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. 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 para-Hydroxy 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.
