Hydroxylamine (also known as hydroxyammonia) is an inorganic compound with the chemical formula . The compound exists as hygroscopic colorless crystals. Hydroxylamine is almost always provided and used as either an aqueous solution or, more often, as one of its salts, such as hydroxylammonium sulfate, a water-soluble solid.
Hydroxylamine and its salts are consumed almost exclusively to produce Nylon-6. The oxidation of Ammonia| to hydroxylamine is a step in biological nitrification.
