Products Description of Hydroxylamine Sulfate CAS#10039-54-0
Hydroxylamine sulfate, alternatively named hydroxylammonium sulfate (HS, molecular formula (NH₂OH)₂·H₂SO₄), presents as colourless crystalline solids. It dissolves freely in water while only exhibiting slight solubility in alcohols. Its aqueous solution is corrosive to human skin, hence careful manipulation is mandatory during operation.
This chemical substance enjoys broad utilisation as a reducing agent, photographic developing agent and purifier for aldehydes and ketones. It also covers numerous application scenarios including organic synthesis, textile auxiliary chemicals, antioxidant stabilisers for fatty acids, catalyst preparation, biological and biochemical research, oxime synthesis for coatings and varnishes, as well as metal anti-rust treatment.

Product Applications of Hydroxylamine Sulfate CAS#10039-54-0
Hydroxylammonium sulfate is a multi-functional chemical with extensive uses spanning industrial manufacturing and laboratory research. Within the photographic industry, it acts as a reducing agent; in polymerisation procedures, it functions as a catalyst, swelling agent and copolymerisation retardant.
For organic synthetic workflows, it serves as textile auxiliary, antioxidant and purifying reagent for aldehydes and ketones. It can transform aldehydes and ketones into oximes, while converting acid chlorides into hydroxamic acids as well.
Other major application fields cover the manufacture of oxime intermediates for coatings and varnishes, metal anti-rust treatment, colour-free short-stopping agents for synthetic rubber, leather dehairing processes, together with biological and biochemical experimental studies.
