1,3-Bis(4-bromophenyl)-1H-imidazol-3-ium bromide (CAS 1621307-01-4), molecular formula C15H11Br2N2Br and molecular weight 458.98 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Bis(4-bromophenyl)-1H-imidazol-3-ium bromide (C15H11Br2N2Br) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
