Meaning and Definition

A yellow crystalline compound with the formula C₆H₄O₂, existing in two isomeric forms (ortho- and para-), used as an oxidizing agent and in the synthesis of dyes and pharmaceuticals.

In biochemistry, a class of quinone derivatives derived from benzene, important as electron acceptors in biological redox reactions, notably in mitochondrial electron transport chains (e.g., ubiquinone).

FAQ

Frequently Asked Questions

Yes, it is toxic and a strong irritant. It must be handled with appropriate safety precautions in a laboratory setting.

Benzoquinone is the oxidised form, while hydroquinone is the reduced form. They are interconvertible via redox reactions.

As a core structure in biologically essential quinones like ubiquinone (CoQ10) in mitochondria, and in some defensive secretions of beetles (e.g., bombardier beetle).

It's a fundamental building block and oxidizing agent used in synthesising dyes, pharmaceuticals, and as a model compound in studying redox chemistry and quinoid systems.
