Description

General description

Silver sulfate (Ag2SO4) is a disilver(I) salt of sulfuric acid. It participates in the TiO2-assisted photooxidation of substituted benzyltrimethylsilanes in acetonitrile. Diarylethanes were obtained in 50-74% yields.

Application

Silver sulfate may be employed in the preparation of the following:
• Iodination reagent in combination with iodine for the synthesis of iododerivatives.
• Silver sulfate reagent, which is required for the determination of Chemical Oxygen Demand (COD).

Packaging
