Chemical Structure

Eperisone Impurity 17 CAS 1805778-90-8 chemical structure

Description

The molecular framework of Eperisone Impurity 17 (C12H15ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Eperisone Impurity 17 (CAS 1805778-90-8) is a certified pharmaceutical impurity reference standard with the molecular formula C12H15ClO and a molecular weight of 210.70 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), Eperisone Impurity 17 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.
