Description
CATO manufactures Flupentixol EP Impurity H DiHCl (E/R-Isomer) 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.
Flupentixol EP Impurity H DiHCl (E/R-Isomer) (CAS CATO-C4X-189540) is a certified pharmaceutical impurity reference standard with the molecular formula C23H25F3N2OSHCl and a molecular weight of 470.98 g/mol.
Based on its molecular formula C23H25F3N2OSHCl, Flupentixol EP Impurity H DiHCl (E/R-Isomer) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 470.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
