Hydroxylamine Sulfate CAS#10039-54-0
Highly soluble in water with moderate solubility in alcohol, facilitating versatile applications.
Functions effectively as a reducing agent and photographic developer.
Used in chemical synthesis, including the purification of aldehydes and ketones.
Serves multiple industrial roles such as oxidation inhibitor, catalyst, rustproofing agent, and in biological research.
Hydroxylammonium sulfate, also known as HS, (NH2OH)2·H2SO4, appears as colorless crystals that dissolve readily in water and are slightly soluble in alcohol. Its solution can be corrosive to the skin. It is widely used as a reducing agent, photographic developer, and purification agent for aldehydes and ketones. Additionally, it plays roles in chemical synthesis, textile processing, fatty acid oxidation inhibition, catalysis, biological and biochemical research, oxime production for paints and varnishes, and rust prevention.

Hydroxylammonium sulfate functions as a reducing agent in photography and serves as a catalyst, swelling agent, and copolymerization inhibitor during polymerization processes. It is used in chemical synthesis, textile applications, and as an oxidation inhibitor. Additionally, it is involved in the production of oximes for paints and varnishes, rustproofing, nondiscoloring short-stoppers for synthetic rubbers, and unhairing hides. It is also utilized in biological and biochemical research, acts as a purification agent for aldehydes and ketones, and converts aldehydes and ketones into oximes as well as acid chlorides into hydroxamic acids.
