 The Hydrazine, with the CAS registry number 302-01-2,is also known as Nitrogen hydride. It belongs to the product categories of Nitrogen Compounds;Organic Building Blocks. This chemical's molecular formula is H₄N₂ and molecular weight is 32.04.Its EINECS number is 206-114-9. What's more,Its systematic name is Hydrazine. It is a colourless oily liquid which is used as fuel in emergency power systems.And it is stability .And it may be an explosion hazard, particularly if heated. Also it is incompatible with sources of ignition, light, shock, strong oxidizing agents, strong acids, metal oxides, nitrous oxide.

Safety Information of Hydrazine:
The Hydrazine is toxic by inhalation, in contact with skin and if swallowed and irritating to eyes, respiratory system and skin. It may form explosive peroxides,so it should be avoided exposure - obtain special instructions before use. And it is toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment,so it should be avoided release to the environment. Refer to special instructions / safety data sheets. And this material and its container must be disposed of as hazardous waste. This chemical  cause cancer. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) .When you use it ,wear suitable protective clothing, gloves and eye/face protection. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

Production of Hydrazine:
Hydrazine is produced in the Olin Raschig process from sodium hypochlorite (the active ingredient in many bleaches) and ammonia, a process announced in 1907. Another route of hydrazine synthesis involves oxidation of urea with sodium hypochlorite:
(H₂N)₂C=O + NaOCl + 2NaOH → N₂H₄ + H₂O + NaCl + Na₂CO₃
It can be synthesized from ammonia and hydrogen peroxide in the Puck process, according to the following formula:
2NH₃ + H₂O₂ → H₂N-NH₂ + 2H₂O
It can also be produced via the so-called ketazine and peroxide processes.

Uses of Hydrazine:
The majority use of hydrazine is as a precursor to blowing agents. It is also used as a propellant onboard space vehicles. Hydrazine (CAS NO.302-01-2) 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 fuels and to prepare the gas precursors used in air bags.

The toxicity data of Hydrazine are as follows:
