Fenton’s reagent was developed in the 1890s by Henry John Horstman Fenton as an analytical reagent (Fenton and Jones 1900). It is a solution of hydrogen peroxide and an iron catalyst. Iron(II) sulfate is a typical iron compound in Fenton’s reagent.

The mechanism mostly accepted today, suggested by Haber and Weiss in the 1930s (Haber and Weiss 1932), is that iron(II) is oxidized by hydrogen peroxide to iron(III), a hydroxyl radical and a hydroxide anion (reaction 1):
$$ {\mathrm{Fe}}^{2+} + {\mathrm{H}}_2{\mathrm{O}}_2\to\ {\mathrm{Fe}}^{3+} + \mathrm{O}\mathrm{H}\cdotp + {\mathrm{O}\mathrm{H}}^{-} $$
