Chemical Structure

Rivaroxaban Impurity 67 CAS 1313613-18-1 chemical structure

Description

The occurrence of Rivaroxaban Impurity 67 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Rivaroxaban Impurity 67 (CAS 1313613-18-1), a pharmacopoeial impurity reference standard (molecular formula C18H18N2O4, MW 326.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H18N2O4, Rivaroxaban Impurity 67 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Rivaroxaban Impurity 67 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.
