Chemical Structure

Tolperisone Impurity 3 CAS 91625-74-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 281.82 g/mol gives Tolperisone Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tolperisone Impurity 3 (CAS 91625-74-0), a pharmacopoeial impurity reference standard (molecular formula C16H23NOHCl, MW 281.82 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Tolperisone Impurity 3 (C16H23NOHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 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.

As a certified reference material (CRM), Tolperisone Impurity 3 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.
