Application

1. Ammonium thiosulfate is used as a bactericide and analytical reagent in medicine.

2. Ammonium thiosulfate is used in agriculture to synthesize the intermediate of the insecticide buprofezin, isobutyl isothiocyanate, and the insecticide, zodiazepine, fungicide, leaf azole, herbicide flufenacetate, etc. The intermediate thiosemicarbazide.

3. In addition, it is also used in the manufacture of auxiliary materials and dyes for hydrogen peroxide, organically synthesized polymerization catalysts and the like.

4. In the photographic industry, it is used as a photographic fixer, which is more soluble in silver halide than sodium salt and has the advantages of short washing time and easy silver recovery.

5. This product is also used as the main component of the silver plating bath in the industry. It is used as a complexing agent in the non-cyanide plating, and the thiosulfate is combined with the silver ion to form a complexion of thiosulfate sulfate. The cathode polarization is enhanced to make the silver plating layer crystallized and the covering ability is good. The general dosage is 200-250 g/L. Also used in the synthesis of organic boron compounds, plasticizers, welding flux; metal surface detergent; aluminum-magnesium alloy casting protection agent.
