2,5-Dihydroxy-1,4-benzoquinone or 2,5-dihydroxy-para-benzoquinone is an organic compound with formula C6H4O4, formally derived from 1,4-benzoquinone by replacing two hydrogen atoms with hydroxyl (OH) groups. It is one of seven dihydroxybenzoquinone isomers. It is a yellow solid with planar molecules that exhibits ferroelectric properties. The compound is a weak acid: one or both hydroxyls can lose a proton to yield the anions C6H3O−4 (pKa1 = 2.95) and C6H2O2−4 (pKa2 = 4.87), respectively. The latter forms a variety of metal complexes, functioning as a binucleating ligand.

  • 2,5-Dihydroxy-1,4-benzochinon (DHBQ) ist ein 1,4-Benzochinon mit zwei Hydroxygruppen, dessen Diketon- und Hydroxy-Funktionalitäten jeweils para-ständig zueinander angeordnet sind. Die Verbindung wurde als eine der Hauptkomponenten bei der Alterung und Vergilbung von Cellulose identifiziert. Wegen seiner elektronischen und magnetischen Eigenschaften findet DHBQ Anwendungen in Metallkomplexen, MOFs und Akkumulatoren. Die Verbindung ist auch als Synthesebaustein (engl. building block), insbesondere für Farbstoffe und Pigmente, von Interesse. (de)
