Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pitavastatin Impurity 57.
Pitavastatin Impurity 57 (CAS CATO-C4X-103757) is a certified pharmaceutical impurity reference standard with the molecular formula C37H30FNPBr and a molecular weight of 618.53 g/mol.
Based on its molecular formula C37H30FNPBr, Pitavastatin Impurity 57 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 618.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 57 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.
