Chemical Structure

Vonoprazan Fumarate Impurity 123 CAS CATO-C4X-1020123 chemical structure

Description

The occurrence of Vonoprazan Fumarate Impurity 123 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Vonoprazan Fumarate Impurity 123 (CAS CATO-C4X-1020123) is a certified pharmaceutical impurity reference standard with the molecular formula C22H19FN2O10SC2HF3O2 and a molecular weight of 636.48 g/mol.

Based on its molecular formula C22H19FN2O10SC2HF3O2, Vonoprazan Fumarate Impurity 123 contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 636.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Vonoprazan Fumarate Impurity 123 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.
