76458-91-8 A838711 N-(4-bromophenyl)-2-oxidanylidene-2-phenyl-ethanehydrazonoyl bromide N-(4-bromophenyl)-2-oxo-2-phenylethanehydrazonoyl bromide CAS 76458-91-8 chemical structure

Description

76458-91-8 A838711 N-(4-bromophenyl)-2-oxidanylidene-2-phenyl-ethanehydrazonoyl bromide N-(4-bromophenyl)-2-oxo-2-phenylethanehydrazonoyl bromide (C14H10Br2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 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.
