Description
CATO supplies Vilazodone impurity 18 (CAS CATO-C4X-135518), a pharmacopoeial impurity reference standard (molecular formula C13H13ClN2, MW 232.71 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Vilazodone impurity 18 (C13H13ClN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Vilazodone impurity 18 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.
