Hydrazine is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings. Hydrazine Test Method, in which several solutions have been formulated as a Hydrazine Reagent. The method is both sensitive and easy to perform. It is used mostly for the determination of small amounts of hydrazine in boiler feedwater.
