UDMH

From Free net encyclopedia

Unsymmetrical dimethylhydrazine (UDMH) (1,1-Dimethylhydrazine) is a hypergolic rocket fuel ingredient, often used in combination with the oxidiser nitrogen tetroxide. UDMH is toxic, a carcinogen and can explode in the presence of oxidisers. During the 1980s there was concern about the levels of UDMH in various foods being a cancer risk, especially for apple juice.

UDMH is a derivative of hydrazine and can be called a hydrazine too. See that article for properties of hydrazines.

UDMH is also used as a nitrogen source in metalorganic vapour phase epitaxy thin-film deposition.
