Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 146.58 g/mol gives Zanamivir EP Impurity F(HCl) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, Zanamivir EP Impurity F(HCl) (CAS 4023-02-3, C4H6N4HCl) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a nitrile group, chlorine substitution, Zanamivir EP Impurity F(HCl) is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Zanamivir EP Impurity F(HCl) 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.
