1,1-Dimethylhydrazine
Physical Description
Descriptions:
- 1,1-dimethylhydrazine appears as a clear colorless liquid with an ammonia-like odor. Flash point 0 °f. Corrosive to the skin. Less dense than water and soluble in water. Vapors are heavier than air and very toxic by inhalation, attacking the eyes and respiratory system. Prolonged exposure of containers to heat may result in their violent rupturing and rocketing due to decomposition. Generates toxic oxides of nitrogen when burned. Vapors may travel to a source of ignition and a flame can flashback to the source of vapors. Used as a rocket propellant and to make other chemicals.
- Colorless liquid with an ammonia- or fish-like odor; [niosh]
