Products Description
Hydroxylamine sulfate, also known as hydroxylammonium sulfate (HS, (NH₂OH)₂·H₂SO₄), appears as colorless crystals that are soluble in water and slightly soluble in alcohol. Its aqueous solution is corrosive to the skin and should be handled with care.
This compound is widely used as a reducing agent, photographic developer, and purification agent for aldehydes and ketones. It also finds applications in chemical synthesis, textile chemicals, oxidation inhibition for fatty acids, catalysis, biological and biochemical research, oxime production for paints and varnishes, and rustproofing.

Product Applications
Hydroxylammonium sulfate is a versatile chemical with multiple industrial and research applications. It is used as a reducing agent in photography, and as a catalyst, swelling agent, and copolymerization inhibitor in polymerization processes.
In chemical synthesis, it serves as a textile chemical, oxidation inhibitor, and purification agent for aldehydes and ketones. It is also used to convert aldehydes and ketones to oximes, and acid chlorides to hydroxamic acids.
Additional applications include the production of oximes for paints and varnishes, rustproofing, nondiscoloring short-stoppers for synthetic rubbers, unhairing hides, and biological and biochemical research.
