Esomeprazole Impurity 130 CAS CATO-C4X-1112130

Description

The occurrence of Esomeprazole Impurity 130 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Esomeprazole Impurity 130 (CAS CATO-C4X-1112130) is a certified pharmaceutical impurity reference standard with the molecular formula C17H18N4O5S and a molecular weight of 390.41 g/mol.

Esomeprazole Impurity 130 (C17H18N4O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), Esomeprazole Impurity 130 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.
