Chemical Structure
Description
As a certified reference material (CRM), (E)-2-(2,4-dichlorostyryl)-1-(4-(trifluoromethyl)benzyl)-1H-benzo[d]imidazole 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.
(E)-2-(2,4-dichlorostyryl)-1-(4-(trifluoromethyl)benzyl)-1H-benzo[d]imidazole (CAS 321433-13-0), molecular formula C23H15Cl2F3N2 and molecular weight 447.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-2-(2,4-dichlorostyryl)-1-(4-(trifluoromethyl)benzyl)-1H-benzo[d]imidazole (C23H15Cl2F3N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
