Description

2-Ethylanthraquinone is an organic compound that is a derivative of anthraquinone. It is commonly used in the industrial production of hydrogen peroxide (H2O2) due to its high selectivity. Another major application is the production of dyes2. It can also be used as a photo-initiator of crosslinking or degradation of polyethylene3.
