Chemical Structure
Description
The molecular framework of 6-Chloro-1-((3-chlorobenzyl)oxy)-2-(4-chlorophenyl)-1H-benzo[d]imidazole (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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 6-Chloro-1-((3-chlorobenzyl)oxy)-2-(4-chlorophenyl)-1H-benzo[d]imidazole (CAS 338978-85-1), a certified reference material (molecular formula C20H13Cl3N2O, MW 403.69 g/mol) for analytical method development and quality control.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
