Used as a reducing agent in analytical chemistry, particularly in the determination of nitrate and nitrite levels in water and soil samples. It is commonly employed to prepare oximes from aldehydes and ketones in organic synthesis. Plays a key role in the conversion of aromatic nitro compounds to hydroxylamines, which is useful in the production of pharmaceuticals and agrochemicals. Also used as a starting material for hydrazines and derivatives in the manufacture of explosives and rocket fuels. Employed in photographic developers, as a stabilizer in polymerization reactions, and for reducing certain oxidizers in laboratory analysis. Its reducing properties make it suitable for removing residual oxidizing agents in industrial processes.
