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)
[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 ...
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 ...
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]
Other important examples are 1,2-benzoquinone (ortho-quinone), 1,4-naphthoquinone and 9,10-anthraquinone. The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. [ 4 ]
Sudocrem (/ ˈ s u d ə k r ɛ m / or / ˈ s u d ə k r i m / in Ireland) [3] is an over-the-counter medicated cream aimed primarily at the treatment of irritant diaper dermatitis.It contains a water-repellent base (consisting of oils/waxes); protective and moisturizer agents; antibiotic and antifungal agents; and a weak anesthetic.
