4-bromo-1-methyl-1H-benzo[d]imidazole-2-carbaldehyde CAS 958863-76-8

Description

The molecular framework of 4-bromo-1-methyl-1H-benzo[d]imidazole-2-carbaldehyde (C9H7BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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).

4-bromo-1-methyl-1H-benzo[d]imidazole-2-carbaldehyde (CAS 958863-76-8), molecular formula C9H7BrN2O and molecular weight 239.07 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 4-bromo-1-methyl-1H-benzo[d]imidazole-2-carbaldehyde meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
