Chemical Structure
Description
Picosulfate EP Impurity C (CAS CATO-C4X-12373) is a certified pharmaceutical impurity reference standard with the molecular formula C18H13NO8S2Na and a molecular weight of 458.41 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Picosulfate EP Impurity C is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 458.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 EP Impurity C 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.
