Uses and applications

What the substance is used for, by industry and function

Insecticide synergist used with pyrethrins and allethrin.

Pharmacological actions

  • Insecticides

How it is made

By addition of n-octyl mercaptan to isosafrole, thioether so formed distils at 183-186 °c/1 mm. The thioether is oxidized by the addition of hydrogen peroxide to an acetone solution, acetone & water being removed by distillation in vacuo.
