Hydrazine - Wikipedia
Hydrazine is an inorganic compound with the chemical formula N 2 H 4. It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly hazardous unless handled in solution as, for example, hydrazine hydrate (N 2 H 4 ·xH 2 O).
