Chemical Structure

Eperisone Impurity 49 TFA CAS CATO-C4X-227949 chemical structure

Description

Based on its molecular formula C16H23NO2C2HF3O2, Eperisone Impurity 49 TFA contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 375.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

CATO supplies Eperisone Impurity 49 TFA (CAS CATO-C4X-227949), a pharmacopoeial impurity reference standard (molecular formula C16H23NO2C2HF3O2, MW 375.39 g/mol) used for the identification and quantification of trace impurities in APIs.

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), Eperisone Impurity 49 TFA 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.
