Monomethylhydrazine (MMH) is a highly toxic, volatile hydrazine derivative with the chemical formula CH 6 N 2. It is used as a rocket propellant in bipropellant rocket engines because it is hypergolic with various oxidizers such as nitrogen tetroxide (N 2 O 4) and nitric acid (HNO 3). As a propellant, it is described in specification MIL-PRF ...
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 ...
Methylhydrazines are hydrazines that have additional methyl groups. Heavily methylated versions exist as hydrazinium salts. Members of this class include: Monomethylhydrazine. Monomethylhydrazinium (cationic and exists as a variety of salts) Dimethylhydrazines. Symmetrical dimethylhydrazine (1,2-dimethylhydrazine)
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).
The attendant wears a full hazmat suit due to the hazards of the hypergolic fuel hydrazine, here being loaded onto the MESSENGER space probe. A hypergolic propellant is a rocket propellant combination used in a rocket engine, whose components spontaneously ignite when they come into contact with each other.

Gyromitrin is a volatile, water-soluble hydrazine compound that can be hydrolyzed in the body into monomethylhydrazine (MMH) through the intermediate N-methyl-N-formylhydrazine. [4] Gyromitrin mechanism of action. Other N-methyl-N-formylhydrazone derivatives have been isolated in subsequent research, although they are present in smaller amounts ...
Direct comparison of physical properties, performance, cost, storability, toxicity, storage requirements and accidental release measures for hydrogen peroxide, hydroxylammonium nitrate (HAN), hydrazine and various cold gas monopropellants shows that hydrazine is the highest performing in terms of specific impulse. However, hydrazine is also the ...
