Applications

Hydroxylamine is a reactant used for the preparation of hydroxyaminoguanidines which are anti-cancer agents, carboxamide derivatives of ofloxacin and human immunodeficiency virus (HIV) integrase inhibitors. It reacts with chlorosulfonic acid to give hydroxylamine-O-sulfonic acid, a useful reagent in the synthesis of caprolactam. It is commonly used as a reducing agent in myriad of organic and inorganic reactions. It acts as an antioxidant for fatty acids. It is widely used to prepare oximes, an important functional group.

Notes

It can violently decompose at elevated temperatures. May be shock-sensitive if dry. Do not heat over 500C. Incompatible with bases, oxidizing agents, nitrates, nitrites, heavy metals, rubber, metals, epoxides and polyester.
