Description
CATO manufactures Flupentixol Dihydrochloride EP Impurity G 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 Dihydrochloride EP Impurity G (CAS 1693-28-3) is a certified pharmaceutical impurity reference standard with the molecular formula C14H7F3OS and a molecular weight of 280.26 g/mol.
Based on its molecular formula C14H7F3OS, Flupentixol Dihydrochloride EP Impurity G contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
