Symmetrical dimethylhydrazine (SDMH), or 1,2-dimethylhydrazine, is the organic compound with the formula (CH 3 NH) 2. It is one of the two isomers of dimethylhydrazine . Both isomers are colorless liquids at room temperature, with properties similar to those of methylamines .
Dimethylhydrazine is the name of two compounds with the molecular formula C 2 H 8 N 2. These are: unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine), with both methyl groups bonded to the same nitrogen atom; symmetrical dimethylhydrazine (1,2-dimethylhydrazine), with one methyl group bonded to each of the two nitrogen atoms
Unsymmetrical dimethylhydrazine (abbreviated as UDMH; also known as 1,1-dimethylhydrazine, heptyl or Geptil) is a chemical compound with the formula H 2 NN(CH 3) 2 that is primarily used as a rocket propellant. [4] At room temperature, UDMH is a colorless liquid, with a sharp, fishy, ammonia-like smell typical of organic amines.

1,1-dimethylhydrazine (unsymmetrical dimethylhydrazine, UDMH) and 1,2-dimethylhydrazine (symmetrical dimethylhydrazine) are hydrazines where two hydrogen atoms are replaced by methyl groups. UDMH is the easier of the two to manufacture and is a fairly common rocket fuel.
Friday’s report from the Commerce Department showed that consumer prices rose 2.6% in December from a year earlier, up from a 2.4% annual pace in November and the third straight increase.
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 ...
