Chemical Structure

Rivaroxaban Impurity 57 CAS 1082495-22-4 chemical structure

Description

The occurrence of Rivaroxaban Impurity 57 is closely related to an amino-acid-derived structure, 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 57 (CAS 1082495-22-4), a pharmacopoeial impurity reference standard (molecular formula C10H12N2O2, MW 192.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Rivaroxaban Impurity 57 (C10H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
