6-Chloro-1-((2,4-dichlorobenzyl)oxy)-2-(4-methoxyphenyl)-1H-benzo[d]imidazole CAS 329235-03-2 chemical structure

Description

The occurrence of 6-Chloro-1-((2,4-dichlorobenzyl)oxy)-2-(4-methoxyphenyl)-1H-benzo[d]imidazole is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Chloro-1-((2,4-dichlorobenzyl)oxy)-2-(4-methoxyphenyl)-1H-benzo[d]imidazole (CAS 329235-03-2) is a high-purity analytical reference standard with the molecular formula C21H15Cl3N2O2 and a molecular weight of 433.72 g/mol.

Structurally, 6-Chloro-1-((2,4-dichlorobenzyl)oxy)-2-(4-methoxyphenyl)-1H-benzo[d]imidazole (C21H15Cl3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 433.72 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
