Use

Hydrazine is used as a high-energy rocket fuel, as a reducing agent, and for preparing organic hydrazine derivatives. The propellant grade of commercial hydrazine is more than 97.7% active. It is also used as an oxygen scavenger in boiler water. Hydrazine has also been used as an experimental drug for treating tuberculosis and sickle cell anemia. It is an reducing agent for many transition metals and some nonmetals (arsenic, selenium, tellurium), as well as uranium and plutonium; corrosion inhibitor in boiler feedwater and reactor cooling water; waste water treatment; electrolytic plating of metals on glas.
