  • Applications

    Ethyl hydroperoxide is an organic hydroperoxide that can generate free radicals; in industry it is used as a radical initiator for free-radical polymerization and as an oxidizing agent in organic synthesis; it can serve as an intermediate for preparing other hydroperoxides and related oxidation products; in coatings and inks, it is considered a source of radicals to promote curing via oxidative radical mechanisms; it is also used in industrial oxidation processes where controlled peroxide delivery is advantageous. All usage is subject to local regulations and formulation limits.
