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: 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] [11] In humans, the most common form of coenzymes Q is coenzyme Q 10, also called CoQ 10 (/ ˌ k oʊ k j uː ˈ t ɛ n /) or ubiquinone-10. [1] Coenzyme Q 10 is a 1,4-benzoquinone, in which "Q" refers to the quinone chemical group and "10" refers to the number of isoprenyl chemical subunits (shown enclosed in brackets in the diagram) in ...
2 to oxygen: dihydroanthraquinone + O 2 → anthraquinone + H 2 O 2. in this way, several million metric tons of H 2 O 2 are produced annually. [12] 1,4-Naphthoquinone, derived by oxidation of naphthalene with chromium trioxide. [13] It is the precursor to anthraquinone.
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C 6 H 4 (OH) 2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also ...
The most common form of plastoquinone, known as PQ-A or PQ-9, is a 2,3-dimethyl-1,4-benzoquinone molecule with a side chain of nine isoprenyl units. There are other forms of plastoquinone, such as ones with shorter side chains like PQ-3 (which has 3 isoprenyl side units instead of 9) as well as analogs such as PQ-B, PQ-C, and PQ-D, which differ ...
Side effects may occur from sudden discontinuation and prolonged, continuous use can lead to skin thinning. [2] Intermittent use of topical steroids for atopic dermatitis is safe and does not cause skin thinning. [3] [4] [5]
The molecular formula C 6 H 4 O 6 (molar mass: 172.09 g/mol, exact mass: 172.0008 u) may refer to: Tetrahydroxy-1,4-benzoquinone; Tetrahydroxy-1,2-benzoquinone
