Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 421.46 g/mol gives Pitavastatin Impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pitavastatin Impurity 7 (CAS 769908-13-6) is a certified pharmaceutical impurity reference standard with the molecular formula C25H24FNO4 and a molecular weight of 421.46 g/mol.
The molecular framework of Pitavastatin Impurity 7 (C25H24FNO4) is characterized by a flavonoid core, 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 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.
CATO manufactures Pitavastatin Impurity 7 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.
