Hydrazine is an inorganic compound with the chemical formula N 2 H 4.It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour.Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
Gyromitrin is metabolized into monomethyl hydrazine. Isoniazid, iproniazid, hydralazine, and phenelzine are medications whose molecules contain hydrazine-like structures. 2,4-dinitrophenylhydrazine (2,4-DNPH) is commonly used to test for ketones and aldehydes in organic and clinical chemistry. phenylhydrazine, C 6 H 5 NHNH 2, the first ...

When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [10] R 2 C=N−NH 2 + R 2 C=O → R 2 C=N−N=CR 2 + H 2 O. Hydrazones are intermediates in the Wolff–Kishner reduction. Hydrazones are reactants in hydrazone iodination, the Shapiro reaction, and the Bamford–Stevens reaction to ...
Hydrazine has physical properties that are remarkably similar to those of water: its melting and boiling points are 2.0 °C and 113.5 °C, the density of the solid at −5 °C is 1.146 g/cm 3, while that of the liquid at 25 °C is 1.00 g/cm 3. [5] The azanes are a series which include ammonia, hydrazine and triazane.
diazane (or hydrazine), N 2 H 4 - two nitrogen and four hydrogen triazane, N 3 H 5 - three nitrogen and five hydrogen. Azanes with three or more nitrogen atoms are named by adding the suffix-azane to the appropriate numerical multiplier prefix. Hence, triazane, N 3 H 5; tetrazane or tetraazane, N 4 H 6; pentazane or pentaazane, N 5 H 7 ...
The peroxide process is a method for the industrial production of hydrazine. In this process hydrogen peroxide is used as an oxidant instead of sodium hypochlorite, which is traditionally used to generate hydrazine. The main advantage of the peroxide process to hydrazine relative to the traditional Olin Raschig process is that it does not ...
In the common names of such salts, the cation is often called "hydrazine", as in "hydrazine sulfate" for hydrazinium hydrogensulfate. The terms "hydrazinium" and "hydrazine" may also be used for the doubly protonated cation [N 2 H 6] 2+, more properly called hydrazinediium or hydrazinium(2+). This cation has an ethane-like structure ([H 3 N− ...
