DOT Classification:  Forbidden

Ethyl hydroperoxide Specification

 Ethyl hydroperoxide with cas registry number of 3031-74-1 is also known as Hydroperoxide, ethyl ; Ethyl hydrogen peroxide . It is stable under normal temperatures and pressures but it also should be stored in a tightly closed container when not in use and stored in a cool, dry place. Ethyl hydroperoxide with cas registry number of 3031-74-1 is used as a pharmaceutical intermediate. It can be used to produce singlet molecular oxygen by decomposition.
