[[File:Hydrazone-2D.png|thumb|right|150px|General structure of a hydrazone]]
A '''hydrazone''' is the [[functional group]] with structure R<sub>1</sub>R<sub>2</sub>C=NNH<sub>2</sub>. They are like [[aldehyde]]s or [[ketone]]s, with an NNH<sub>2</sub> group instead of the [[oxygen]] atom.
They are made by [[chemical reaction|reacting]] [[hydrazine]]s with ketones or aldehydes:

Hydrazones are very useful [[molecule]]s to do some reactions. For example, a ketone can be [[reduction|reduced]] down completely if made into a hydrazine and then treated with [[sodium ethoxide]] ([[Wolff–Kishner reduction]]). Hydrazones are very important [[intermediate]]s in many reactions, such as the [[Fischer indole synthesis]]. This makes [[indole]]s, groups which are found in many [[drug]]s.
