| dbo:abstract | La tétrahydroxy-1,4-benzoquinone aussi appelée tétrahydroxy-p-benzoquinone, tétrahydroxybenzoquinone et même tétrahydroxyquinone (THBQ, THQ) est un composé organique de formule C6O2(OH)4. Cette molécule est composé d'un cycle cyclohexadiène avec, comme substituants, quatre groupes hydroxyle et deux groupes cétone en positions opposées c'est-à-dire "para". Ce composé donne des solutions aqueuses rouge clair et forme des cristaux avec un éclat bleu-noir mais non conducteurs du dihydrate C6O2(OH)4·2H2O. La tétrahydroxy-1,4-benzoquinone peut être synthétisée de l'éthanedial ou de l'inositol, un composé naturel largement présent dans des plantes. La THBQ forme un adduit de ratio 2:3 avec la 4,4'-bipyridine. (fr) Tetrahydroxy-1,4-benzoquinone, also called tetrahydroxy-p-benzoquinone, tetrahydroxybenzoquinone, or tetrahydroxyquinone (THBQ, THQ), is an organic compound with formula C6O2(OH)4. Its molecular structure consists of a cyclohexadiene ring with four hydroxyl groups and two ketone groups in opposite (para) positions. The compound gives a light red solution in water, and crystallizes as the glistening bluish-black (but non-conducting) dihydrate C6O2(OH)4·2H2O. The compound can be synthesized from glyoxal or from myo-inositol, a natural compound widely present in plants. THBQ forms an adduct with 4,4′-bipyridine in a 2:3 ratio. (en) Tetrahydroxy-1,4-benzochinon, ook bekend onder de namen: tetrahydroxy-p-benzochinon, tetrahydroxybenzochinon of tetrahydroxychinon (Tetrahydroxybenzoquinon: THBQ of THQ), is een organische verbinding met de formule . De moleculaire structuur kan beschreven worden als een 1,4-cyclohexadieen-ring met vier hydroxylgroepen en twee ketogroepen; de laatste twee staan tegenover elkaar in de ring (para). Tetrahydroxy-1,4-benzochinon is een van de oxidatiestappen in de serie van benzeenhexol naar cyclohexaanhexon. In water vormt de verbinding een licht rode oplossing, hij kristalliseert tot een glimmend, blauw-zwart dihydraat, . De verbinding kan gesynthetiseerd worden uit glyoxaal of uit inositol, een rijkelijk in planten voorkomend natuurproduct. Tetrahydroxy-1,4-benzochinon vormt een adduct met in een verhouding van 2:3.
