Safety & regulation
Hazard information
Regulatory Information
Chemical: Hydroxylamine, sulfate (1:1) (salt)
Hydroxylamine, sulfate (1:1) (salt): Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.
Other Safety InformationIMAP assessments - Hydroxylamine and its salts: Human health tier II assessment
Fire HazardsNot combustible. Gives off irritating or toxic fumes (or gases) in a fire.
EC ClassificationSymbol: Xn, N; R: 22-36/38-43-48/22-50; S: (2)-22-24-37-61
UN ClassificationUN Hazard Class: 9; UN Pack Group: III
Chemical DangersDecomposes on heating. This produces corrosive fumes. The substance is a weak acid. Attacks many metals. This produces flammable/explosive gas (hydrogen - see ICSC 0001).
Safety & protection
Fire FightingUse water in large amounts, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
First Aid Measures
Fresh air, rest. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention .
Safe StorageSeparated from strong bases. Store in an area without drain or sewer access.
Spillage Disposal
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT let this chemical enter the environment.
Eye PreventionWear safety goggles or eye protection in combination with breathing protection.
Fire PreventionNO open flames.
Inhalation RiskA harmful concentration of airborne particles can be reached quickly when dispersed.
Skin PreventionProtective gloves.
Exposure PreventionPREVENT DISPERSION OF DUST!
Ingestion PreventionDo not eat, drink, or smoke during work.

Chemistry & industry
Uses & manufacturing
General Manufacturing InformationHydroxylamine, sulfate (1:1): ACTIVE
Applications
UsesHydroxylammonium sulfate is a reducing agent in photography; catalyst, swelling agent, and copolymerization inhibitor in polymerization processes; in chemical synthesis; as a textile chemieal; as an oxidation inhibitor; in making oximes for paints and varnishes; in rustproofing; in nondiscoloring short -stoppers for synthetic rubbers; for unhairing hides; in biological and biochemical research; as a purification agent for aldehydes and ketones; converts aldehydes and ketones to oximes and acid chlorides to hydroxamic acids.
UsesHydroxylamine sulfate may be used to prepare highly sensitive cellulose tape, used for the detection of formaldehyde gas. It may be used in the quantitative determination of perchlorate in biological fluids by spectrophotometric methods .
UsesAs reducing agent in photography; in synthetic and analytical chemistry; to purify aldehydes and ketones. As antioxidant for fatty acids and soaps. As dehairing agent for hides.
UsesUsed as to purify aldehydes and ketones; reagent for mercury and silver detection in water; reducing agent.
General DescriptionColorless crystalline solid. Contact may cause severe irritation to skin, eyes, and mucous membranes. May be toxic by ingestion.
Preparation methods
PreparationHydroxylamine sulfate may be prepared by mixing stoichiometric amountsof hydroxylamine and sulfuric acid. It also may be prepared by electrolytical-ly reducing an aqueous solution of ammonium sulfate.
