NH2OH, commonly known as hydroxylamine, is a chemical compound with the formula NH2OH. It consists of a hydroxyl group (-OH) attached to an amine group (NH2). Hydroxylamine is a colorless, crystalline solid that is soluble in water and has a faint ammonia-like odor. It is primarily used in organic synthesis and as a reducing agent in various chemical reactions. Hydroxylamine is also important in the production of pharmaceuticals and agrochemicals. It can be used to convert ketones and aldehydes into oximes, which are valuable intermediates in the synthesis of other compounds. Additionally, hydroxylamine plays a role in the preparation of nitroxides, which are stable free radicals used in various applications, including materials science and biochemistry.
