Hydroxylamine, 50% aq. soln.

Description

CAS: 7803-49-8 | H3NO | 33.03 g/mol

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.
