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.
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 .
Hydrazines (R 2 N−NR 2) are a class of chemical compounds with two nitrogen atoms linked via a covalent bond and which carry from one up to four alkyl or aryl substituents. . Hydrazines can be considered as derivatives of the inorganic hydrazine (H 2 N−NH 2), in which one or more hydrogen atoms have been replaced by hydrocarbon grou
Symmetrical dimethylhydrazine (1,2-dimethylhydrazine) Unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine) Trimethylhydrazine. 1,1,2-trimethylhydrazine; 1,1,1-trimethylhydrazinium (cationic and exists as a variety of salts e.g. 1,1,1-trimethylhydrazinium iodide) Tetramethylhydrazine. 1,1,2,2-tetramethylhydrazine

Aerozine 50 is more stable than hydrazine alone, and has a higher density and boiling point than UDMH alone. Pure hydrazine has a higher performance than Aerozine 50, but an inconvenient freezing point of 2 °C. [3] A mix of hydrazine and UDMH has a far lower freezing point due to freezing-point depression.
