Unsymmetrical Dimethylhydrazine (UDMH)

Unsymmetrical dimethylhydrazine (1,1-dimethylhydrazine) is a clear, colorless hygroscopic liquid. It has an ammonia-like odor which closely resembles that of aliphatic amines. UDMH is miscible with water, hydrazine, dimethylhydrazine, ethanol, amines and most petroleum fuels.

UDMH is mildly alkaline and is a very strong reducing agent. Its high chemical reactivity, easily-controlled functionality and strong hydrogen bonding are its most useful properties.
