Chemical Structure
Description
3-Bromo-1-ethyl-1H-1,2,4-triazole (CAS 64907-54-6) is a high-purity analytical reference standard with the molecular formula C4H6BrN3 and a molecular weight of 176.01 g/mol.
Based on its molecular formula C4H6BrN3, 3-Bromo-1-ethyl-1H-1,2,4-triazole contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 176.01 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), 3-Bromo-1-ethyl-1H-1,2,4-triazole 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.
