The hydrogen atom certain to the hydrazine group are not able to only to get taken off by oxidation, bringing about the hydrazyl free radical, but will also by a base, as it has an acidic character. Most of the hydrazyl free radicals have a violet color, although the mum or dad hydrazines are yellow; the corresponding anion is frequently purple-brown, but it really can be done also to be environmentally friendly, depending on the substituents.
