1,4-Benzoquinone, commonly known as para-quinone, is a chemical compound with the formula C 6 H 4 O 2. In a pure state, it forms bright-yellow crystals with a characteristic irritating odor, resembling that of chlorine, bleach, and hot plastic or formaldehyde. This six-membered ring compound is the oxidized derivative of 1,4-hydroquinone. [4]
Benzoquinone (C 6 H 4 O 2) is a quinone with a single benzene ring. There are 2 (out of 3 hypothetical) benzoquinones: 1,4-Benzoquinone, most commonly, right image (also para-benzoquinone, p-benzoquinone, para-quinone, or just quinone) 1,2-Benzoquinone, less commonly, left image (also ortho-benzoquinone, o-benzoquinone, ortho-quinone)
Relative to benzoquinone, more strongly oxidizing quinones include chloranil and 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (also known as DDQ). [6] The oxidizing power of quinones is enhanced by the presence of acids. [7] In acidic conditions, quinone undergoes two-electron and two-proton reduction to hydroquinone.

The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates. The flow of reactants into the reaction chamber and subsequent ejection occur in a series of about 70 pulses, at a rate of about 500 pulses per second. The whole sequence of events takes only a fraction of a second.
The molecular formula C 6 H 4 O 2 (molar mass: 108.09 g/mol, exact mass: 108.0211 u) may refer to: 1,2-Benzoquinone , also called ortho-benzoquinone 1,4-Benzoquinone , also called para-quinone
To a stirred solution of p-(3-hydroxypropyl)phenol (152 mg, 1 mmol) and pyridine (0.3 mL) in acetonitrile (10 mL) at 0° was added a solution of IBTA (430 mg, 1 mmol) in acetonitrile (2 mL). The mixture was stirred at room temperature for 10 minutes, diluted with water, and extracted with diethyl ether (3 × 10 mL).
The IUPAC name is 2-hydroxycyclohexa-2,5-diene-1,4-dione. It is formed by the reaction of 1,4-benzoquinone with hydrogen peroxide and is a byproduct of the metabolism of phenols, such as 1,2,4-benzenetriol. [1] The enzyme 1,2,4-benzenetriol dehydrogenase catalyzes the conversion of 1,2,4-benzenetriol to 2-hydroxy-1,4-benzoquinone, and the ...
