Application

  • Preparation of radiochemicals: Diphenyl sulfoxide plays a role in the synthesis of [(11)C]cyanide from [(11)C]methyl iodide, facilitating rapid and efficient production of radiochemicals for medical imaging applications (Kikuchi et al., 2022).
  • Catalytic oxidation processes: The photocatalytic and catalytic oxidation of diphenyl sulphide to sulfoxide and sulfone was examined, highlighting the effectiveness of hydrogen peroxide and TiO2 polymorphs in optimizing chemical processes (Mikrut et al., 2022).
  • Dielectric properties research: The study on dielectric properties of high organic sulfur coal highlighted the modeling of sulfur compounds, which could include diphenyl sulfoxide, enhancing our understanding of materials science in energy sectors (Cai et al., 2019).
