Task: Please create a text description for a molecule.
Molecule SMILES: O=C([O-])C1=CC(O)OC(C(=O)[O-])=C1
Constraint: Answer the question with complete sentences.
Result: The molecule is a dicarboxylic acid dianion arising from deprotonation of both carboxy groups of 4-carboxy-2-hydroxymuconate semialdehyde hemiacetal; major species at pH 7.3. It is a conjugate base of a 4-carboxy-2-hydroxymuconate semialdehyde hemiacetal.
