1-(4-Chlorobenzyl)-2-(6-chloropyridin-3-yl)-5,6-dimethyl-1H-benzo[d]imidazole (CAS 337920-58-8) is a high-purity analytical reference standard with the molecular formula C21H17Cl2N3 and a molecular weight of 382.29 g/mol.
The molecular framework of 1-(4-Chlorobenzyl)-2-(6-chloropyridin-3-yl)-5,6-dimethyl-1H-benzo[d]imidazole (C21H17Cl2N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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).
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.
