| Para-phenylenedioxane is a type of quinone organic compound. Pure para-phenylenedioxane is a bright yellow crystal with a pungent odor similar to that of chlorine; impure samples often appear dull due to the presence of quinone-hydroquinone (a 1:1 charge-transfer complex formed by para-phenylenedioxane and hydroquinone). Para-phenylenedioxane contains a non-aromatic six-membered ring and is the oxidation product of hydroquinone (para-phenylenediol). | |||||||||
