It is one of three isomers of dinitrobenzene. The 1,4-isomer is most symmetrical. The compound is a yellow solid that is soluble in organic solvents. It is prepared from 4-nitroaniline by diazotization followed by treatment with sodium nitrite in the presence of a copper catalyst.[1] References1. ^{{cite journal|author=E. B.
