Product Application of Hydroxylamine Sulfate CAS#10039-54-0
Hydroxylammonium sulfate acts as a reducing agent for photography. In polymerization, it serves as catalyst, swelling agent and copolymerization inhibitor. It is widely applied in chemical synthesis and textile processing, and works as oxidation inhibitor. It can convert aldehydes and ketones into oximes and transform acid chlorides into hydroxamic acids, and purify aldehydes and ketones. It is also used to prepare oximes for paints and varnishes, for metal rustproofing, producing non-discoloring short-stoppers for synthetic rubber, hide unhairing, as well as biological and biochemical research.
