1,4-Benzoquinone (or, less formally, “quinone”), is a yellow crystalline solid with a chlorine-like odor. It is the simplest member of the quinone family of conjugated dienediones that have several uses in organic chemistry. It undergoes typical ketone and olefin reactions, but its predominant use is as an oxidizing agent. 1,4-Benzoquinone and its reduced form 1,4-dihydroquinone (1,4-dihydroxybenzene) form the basis of many redox systems.
