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 ...
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)
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 ...
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 ...
Monomethylhydrazine (mono-methyl hydrazine, MMH) Index of chemical compounds with the same molecular formula This set index page lists chemical structure articles associated with the same molecular formula .
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).
Hydrazine may also be mixed with monomethyl hydrazine (MMH). Because MMH is slightly denser, net performance is increased slightly. [citation needed]A potentially novel hypergolic alternative has been developed based on tertiary amine azides – called CINCH (Competitive Impulse Non-Carcinogenic Hypergol) and the name of the compound is 2-Dimethylaminoethylazide.
