Cumene hydroperoxide is the organic compound with the formula C6H5C(CH3)2OOH; this oily liquid is classified as an organic hydroperoxide. Products of decomposition of cumene hydroperoxide are methylstyrene, acetophenone, and 2-phenylpropan-2-ol.
It is produced by treatment of cumene with oxygen, an autoxidation. At temperatures >100 °C, oxygen is passed through liquid cumene:
- C
 6H
 5CH(CH

 2 + O2 → C
 6H
 5C(CH

 2OOH
Dicumyl peroxide is a side product.
