Pralidoxime Chloride Impurity 6 (IC7H7N2) contains a nitrile group, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Pralidoxime Chloride Impurity 6 (CAS 3785-03-3) is a certified pharmaceutical impurity reference standard with the molecular formula IC7H7N2 and a molecular weight of 246.05 g/mol.
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 Pralidoxime Chloride Impurity 6 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.
