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 supplies Vortioxetine Impurity 146 TFA (CAS 1429908-33-7 (free base)), a pharmacopoeial impurity reference standard (molecular formula C18H20N2O2SC2HF3O2, MW 442.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Vortioxetine Impurity 146 TFA (C18H20N2O2SC2HF3O2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
CATO manufactures Vortioxetine Impurity 146 TFA 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.
