Brexpiprazole Impurity 3 CAS 1420987-86-5

Description

Compared with other compounds in its class, the molecular weight of 350.50 g/mol gives Brexpiprazole Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Brexpiprazole Impurity 3 (CAS 1420987-86-5), a pharmacopoeial impurity reference standard (molecular formula C20H18N2S2, MW 350.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H18N2S2, Brexpiprazole Impurity 3 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.50 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).

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), Brexpiprazole 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.
