Chemical Structure
Description
The occurrence of 2-Bromo-1-ethyl-1H-imidazole is closely related to a nitrile group, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-1-ethyl-1H-imidazole (CAS 663171-12-8), molecular formula C5H7BrN2 and molecular weight 175.03 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H7BrN2, 2-Bromo-1-ethyl-1H-imidazole contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 175.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-1-ethyl-1H-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.
