Chemical Structure
Description
The molecular framework of 2-(4-Chlorophenyl)-1-((2,4-dichlorobenzyl)oxy)-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).
2-(4-Chlorophenyl)-1-((2,4-dichlorobenzyl)oxy)-1H-benzo[d]imidazole (CAS 338791-26-7) is a high-purity analytical reference standard with the molecular formula C20H13Cl3N2O and a molecular weight of 403.69 g/mol.
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.
