Chemical Structure
Description
CATO supplies 6-Chloro-1-[(2,4-dichlorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (CAS 338978-68-0), a certified reference material (molecular formula C20H13Cl3N2O, MW 403.69 g/mol) for analytical method development and quality control.
The molecular framework of 6-Chloro-1-[(2,4-dichlorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (C20H13Cl3N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 6-Chloro-1-[(2,4-dichlorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole 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.
