Chemical Structure
Description
CATO supplies (E)-4-((3,4-dichlorobenzyl)oxy)-N'-((perfluorophenyl)methylene)benzohydrazide (CAS 303987-45-3), a certified reference material (molecular formula C21H11Cl2F5N2O2, MW 489.22 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4-((3,4-dichlorobenzyl)oxy)-N'-((perfluorophenyl)methylene)benzohydrazide (C21H11Cl2F5N2O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (E)-4-((3,4-dichlorobenzyl)oxy)-N'-((perfluorophenyl)methylene)benzohydrazide 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.
