Picosulfate Impurity 6 CAS CATO-C4X-12376 chemical structure

Description

As a certified reference material (CRM), Picosulfate Impurity 6 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.

Picosulfate Impurity 6 (CAS CATO-C4X-12376) is a certified pharmaceutical impurity reference standard with the molecular formula C18H13NO9S2Na and a molecular weight of 474.41 g/mol.

Picosulfate Impurity 6 (C18H13NO9S2Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).

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.
