Picosulfate Impurity 7 CAS 36175-10-7 chemical structure

Description

CATO supplies Picosulfate Impurity 7 (CAS 36175-10-7), a pharmacopoeial impurity reference standard (molecular formula C20H16NO6SNa, MW 421.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Picosulfate Impurity 7 (C20H16NO6SNa) 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 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.

As a certified reference material (CRM), Picosulfate Impurity 7 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.
