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 ...
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.

When derived from hydrazine itself, hydrazones condense with a second equivalent of a carbonyl to give azines: [11] 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 ...
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 ...
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− ...
There are various methods to synthesize aryl azides. One such method would be to set use react aniline with sodium nitrite (NaNO 2) and hydrazine hydrate in the presence of acetic acid. [2] This reaction will give moderate to good yield of the desired aryl azide. The best solvent for this reaction is dichloromethane.
