Chemical Structure
Description
The molecular framework of Blonanserin Impurity 16 (C21H28FN3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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).
CATO supplies Blonanserin Impurity 16 (CAS CATO-C4X-111016), a pharmacopoeial impurity reference standard (molecular formula C21H28FN3, MW 341.47 g/mol) used for the identification and quantification of trace impurities in APIs.
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), Blonanserin Impurity 16 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.
