Chemical Structure

Ropivacaine EP Impurity E CAS 265120-58-9 chemical structure

Description

Ropivacaine EP Impurity E (C17H26N2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

Ropivacaine EP Impurity E (CAS 265120-58-9) is a certified pharmaceutical impurity reference standard with the molecular formula C17H26N2O and a molecular weight of 274.40 g/mol.

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), Ropivacaine EP Impurity E 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.
