Description
CATO supplies 5-Bromo-2-phenyl-2H-benzo[d][1,2,3]triazole (CAS 1643848-10-5), a certified reference material (molecular formula C12H8BrN3, MW 274.12 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H8BrN3, 5-Bromo-2-phenyl-2H-benzo[d][1,2,3]triazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 5-Bromo-2-phenyl-2H-benzo[d][1,2,3]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.
