Chemical Structure

(E)-1,2-Diphenyldiazene 1-oxide CAS 21650-65-7 chemical structure

Description

(E)-1,2-Diphenyldiazene 1-oxide (C12H10N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
