It is an organic oxidizer that has a chemical structure consists of four nitro groups attached to one carbon atom. In 1857 it was first synthesized by the reaction of sodium cyanoacetamide with nitric acid. In the laboratory, it is used as a reagent for the detection of double bonds in organic compounds and as a nitrating reagent.
