Ecabet Impurity 1 CAS CATO-C4X-16261 chemical structure

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.

Ecabet Impurity 1 (CAS CATO-C4X-16261) is a certified pharmaceutical impurity reference standard with the molecular formula C24H36O5S and a molecular weight of 436.60 g/mol.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, Ecabet Impurity 1 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.60 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), Ecabet Impurity 1 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.
