Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 460.54 g/mol gives Pitavastatin Impurity 73 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Pitavastatin Impurity 73 (CAS CATO-C4X-103773, C25H23FNO4Ca) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Pitavastatin Impurity 73 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 460.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 73 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.
