Hydroxylammonium Sulfate serves as a reducing agent in photography and functions as a catalyst, swelling agent, and copolymerization inhibitor in polymerization processes. It is used in chemical synthesis, textile processing, and as an oxidation inhibitor. Additionally, it plays a role in the production of oximes for paints and varnishes, rustproofing, and in non-discoloring short-stoppers for synthetic rubbers. It is also employed in unhairing hides, biological and biochemical research, and as a purification agent for aldehydes and ketones, converting them into oximes, while transforming acid chlorides into hydroxamic acids.
