偏苯三酚,又稱為羥基氫醌 (HHQ) (英文: Hydroxyhydroquinone、Hydroxyquinol)[1]是一種有機化合物。它是苯三酚三种位置异构物的其中之一。该化合物是一种可溶于水的無色固體,但在接觸空氣後會反應生成黑色不溶性固體。 [2]

製備

工業上的製備方式是先以乙酸酐乙酰化對苯醌,然后水解所產生三乙酸酯来制备。 [2]

在历史上,偏苯三酚則是通过氢氧化钾和对氢醌的反應而产生。 [3]也可通过果糖脱水製得。 [4] [5]

在自然中的發現

偏苯三酚是许多芳香族化合物,例如单氯酚二氯酚以及更複雜的物质如農藥2,4,5-T等 ,在生物降解中常見的中间產物[6]羟基氫醌通常作为兒茶素,一種存在於植物中的天然酚(例如在土壤细菌Bradyrhizobium japonicum 中)[7]生物降解产物而存在於自然界中。羟基氫醌亦是某些生物体的代謝過程中所產生的代谢物,例如 1,2,4-苯三酚 1,2-雙加氧酶這一种就使用偏苯三酚作為底物氧氣反應而产生3-羟基-顺,顺-粘康酸。
