In chemistry, furantetracarboxylic acid is an organic compound with formula C8H4O9, or (C4O)(-(CO)OH)4, which can be viewed as deriving from furan C4H4O through replacement of the four hydrogen atoms by carboxyl functional groups -(CO)OH.
By removal of four protons, the acid is expected to yield the anion C8O4−9, furantetracarboxylate, which is one of the oxocarbon anions (consisting solely of oxygen and carbon. By loss of 1 through 3 protons it forms the anions C8H3O−9, C8H2O2−9, and C8HO3−9, called respectively trihydrogen-, dihydrogen-, and hydrogenfurantetracarboxylate. The same names are used for the corresponding esters.
The acid can be obtained by from dioxalylsuccinate.[1][2][3]
The salt rubidium trihydrogenfurantetracarboxylate RbH3C8O9 crystallizes as white needles.[4]
