4-((2,4-Dichlorobenzyl)oxy)-3-ethoxy-5-iodobenzonitrile (CAS 1706445-44-4), molecular formula C16H12Cl2INO2 and molecular weight 448.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((2,4-Dichlorobenzyl)oxy)-3-ethoxy-5-iodobenzonitrile (C16H12Cl2INO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 4-((2,4-Dichlorobenzyl)oxy)-3-ethoxy-5-iodobenzonitrile 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.
