In
chemistry, furantetracarboxylic acid is an
organic compound with formula C
8H
4O
9, or (C4O)(-(CO)OH)4, which can be viewed as deriving from
furan C
4H
4O 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 C
8O4−
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 C
8H
3O−
9, C
8H
2O2−
9, and C
8HO3−
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 RbH
3C
8O
9 crystallizes as white needles.
