Hydrazine is an inorganic chemical compound with the formula N2H4. It is a colourless liquid with an ammonia-like odor and is derived from the same industrial chemistry processes that manufacture ammonia. However, hydrazine has physical properties that are closer to those of water.
Hydrazine is highly toxic and dangerously unstable, and is usually handled as an aqueous solution for safety reasons.
Hydrazine is mainly used as a foaming agent in preparing polymer foams, but significant applications also include its uses as a precursor to polymerization catalysts and pharmaceuticals . Additionally, hydrazine is used in various rocket fules and to prepare the gas precursors used in air bags. Approximately 260,000 tons are manufactured annually.
