Cumene hydroperoxide is an intermediate in the cumene process for developing phenol and acetone from benzene and propylene. It is typically used as an oxidizing agent.[2] Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone and cumyl alcohol.[3] Its formula is C6H5C(CH3)2OOH.

One of the key uses for the material is as a free radical initiator for acrylate and methacrylates monomers.
