2-Ethylanthraquinone (Powder) is a key organic compound primarily used as the working carrier in the anthraquinone (Riedl-Pfleiderer) process for producing hydrogen peroxide, in which it is hydrogenated over a palladium catalyst and then reoxidised to release hydrogen peroxide. It appears as a pale yellow to white crystalline powder, soluble in organic solvents but insoluble in water. This chemical has a CAS number of 84-51-5, with a molecular formula of C16H12O2 and a molecular weight of 236.27 g/mol. It should be stored at ambient conditions, with a signal word of Warning indicating moderate hazard.
