Pitavastatin Impurity 77 CAS 167934-30-7

Description

Compared with other compounds in its class, the molecular weight of 475.55 g/mol gives Pitavastatin Impurity 77 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pitavastatin Impurity 77 (CAS 167934-30-7) is a certified pharmaceutical impurity reference standard with the molecular formula C29H30FNO4 and a molecular weight of 475.55 g/mol.

The molecular framework of Pitavastatin Impurity 77 (C29H30FNO4) is characterized by a steroid 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.

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.

CATO manufactures Pitavastatin Impurity 77 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.
