5,7-Dibromo-2-phenyl-1H-benzo[d]imidazole CAS 1806-09-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,7-Dibromo-2-phenyl-1H-benzo[d]imidazole.

5,7-Dibromo-2-phenyl-1H-benzo[d]imidazole (CAS 1806-09-3), molecular formula C13H8Br2N2 and molecular weight 352.02 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 5,7-Dibromo-2-phenyl-1H-benzo[d]imidazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 5,7-Dibromo-2-phenyl-1H-benzo[d]imidazole 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.
