2-(4-Chlorophenyl)-1-((3,4-dichlorobenzyl)oxy)-6-nitro-1H-benzo[d]imidazole (CAS 282523-47-1) is a high-purity analytical reference standard with the molecular formula C20H12Cl3N3O3 and a molecular weight of 448.69 g/mol.
The molecular framework of 2-(4-Chlorophenyl)-1-((3,4-dichlorobenzyl)oxy)-6-nitro-1H-benzo[d]imidazole (C20H12Cl3N3O3) 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 the protonation state of its nitrogen-containing groups, 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).
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.
