Chemical Structure
Description
The occurrence of 7-Bromo-2,4-dichloro-1H-benzo[d]imidazole is closely related to a nitrile group, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7-Bromo-2,4-dichloro-1H-benzo[d]imidazole (CAS 1388030-79-2) is a high-purity analytical reference standard with the molecular formula C7H3BrCl2N2 and a molecular weight of 265.92 g/mol.
7-Bromo-2,4-dichloro-1H-benzo[d]imidazole (C7H3BrCl2N2) contains a nitrile group, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 7-Bromo-2,4-dichloro-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.
