Synonyms asym-Dimethylhydrazine un-symmetrical dimethylhydrazine dimazine UDMH... 

A liquid fuel for rocket engines, which is composed of 50% anhydrous hydrazine and 50% asym-dimethylhydrazine. 

Contrary to reports in the literature, the reaction of (dialkylamino)-diboranes with tertiary amines proceeds via an intermediate complex in which the diboranyl group is preserved. The final products are mixtures of aminoboranes and amine-boranes.176 Reactions with sym- and asym-dimethylhydrazines are also reported, giving products such as H2B—NMe— NMe—BH2 and Me2NNH—BH2, respectively.
