Ropinirole EP Impurity G CAS 76149-15-0

Description

Compared with other compounds in its class, the molecular weight of 244.38 g/mol gives Ropinirole EP Impurity G distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ropinirole EP Impurity G (CAS 76149-15-0), a pharmacopoeial impurity reference standard (molecular formula C16H24N2, MW 244.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Ropinirole EP Impurity G (C16H24N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

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), Ropinirole EP Impurity G 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.
