Description
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.
Suplatast Tosilate impurity 83 (CAS CATO-C4X-32683) is a certified pharmaceutical impurity reference standard with the molecular formula C17H30NO4SC7H7O3S and a molecular weight of 515.68 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Suplatast Tosilate impurity 83 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 515.68 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).
As a certified reference material (CRM), Suplatast Tosilate impurity 83 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
