Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 535.51 g/mol gives Piperaquine Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Piperaquine Impurity 8 (CAS 918879-09-1) is a certified pharmaceutical impurity reference standard with the molecular formula C29H32Cl2N6 and a molecular weight of 535.51 g/mol.
Piperaquine Impurity 8 (C29H32Cl2N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Piperaquine Impurity 8 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.
