Zimmermann reagent

It is a two-component reagent, with the first component composed of 1,3-dinitrobenzene (1% w/v) in methanol and the second component composed of 15% potassium hydroxide in water. One drop of each component is added to the sample being tested and the resulting colour change is observed to give an indication of the identity of the compound.
