Hydroxylamine NH2OH - colorless crystals, readily soluble in water with the formation of hydrate NH2OH H2O
The most important salt hydroxylamine is hydrochloric acid NH2OH · HCl. It is used as a reducing agent in inorganic analysis; for the quantitative determination of formaldehyde, furfural, camphor, glucose; in photography and medicine.
Used in organic synthesis. Hydroxylamine, interacting with aldehydes and ketones, forms oximes: R — CH = NOH and R2 — C = NOH.
