Simethicone Impurity N2 CAS 3663-50-1 chemical structure

Description

Simethicone Impurity N2 (CAS 3663-50-1) is a certified pharmaceutical impurity reference standard with the molecular formula C6H20O4Si3 and a molecular weight of 240.48 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Simethicone Impurity N2 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Simethicone Impurity N2 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.
