Hydroxylamine Sulfate CAS 10039-54-0

Hydroxylammonium sulfate serves as a reducing agent in photography and as a catalyst, swelling agent, and copolymerization inhibitor during polymerization. It plays a role in chemical synthesis, textile chemicals, and as an antioxidant. It is also used to produce oximes for manufacturing paints and varnishes and in corrosion prevention. Additionally, it works as a non-staining stopper in synthetic rubber, aids in hair removal, and supports biochemical and organic research. It purifies aldehydes and ketones, converting them into oximes, and transforms acid chlorides into hydroxamic acids.

Applications in Detection and Analysis

Hydroxylamine sulfate enables the preparation of cellulose tape with high sensitivity for detecting formaldehyde gas. Spectrophotometry uses it for the quantitative determination of perchlorate in organic liquids.

Derivatives in Agriculture and Medicine

The oxime or hydroxamic acid derivatives of hydroxylamine sulfate contribute to the production of pesticides like methomyl, aldicarb, and thiomethomyl, as well as fungicides and herbicides. Additionally, it plays a critical role as a reducing agent, developer, and rubber vulcanizing agent. The synthesis of caprolactam, an important material in nylon production, heavily depends on hydroxylamine sulfate. It is also an intermediate in the creation of medicines and pesticides, including isoxazole derivatives, sulfa drugs, and vitamins B5 and B12. Moreover, it supports polymer synthesis and chemical analysis.

Role in Analytical Chemistry

Hydroxylamine sulfate acts as an inorganic reducing agent, reducing compounds of gold, silver, and mercury to their elemental forms. It also reduces Fe3+, Cu2+, and V5+ to lower oxidation states. It finds applications in determining selenium, conducting biological and biochemical research, as a photographic developer, in oxime production, and as a catalyst. It also serves as a swelling agent and polymerization inhibitor in copolymerization reactions and is used for leather hair removal.
