Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3-Chlorophenyl)-1-((2,4-dichlorobenzyl)oxy)-6-nitro-1H-benzo[d]imidazole (CAS 303149-31-7), molecular formula C20H12Cl3N3O3 and molecular weight 448.69 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Chlorophenyl)-1-((2,4-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 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).
CATO manufactures 2-(3-Chlorophenyl)-1-((2,4-dichlorobenzyl)oxy)-6-nitro-1H-benzo[d]imidazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
