Task: Please create a description for a molecule.
SMILES: O=C(O)c1[nH]c(-c2c[nH]c3ccc([O-])cc23)cc1-c1c[nH]c2ccccc12
Constraint: Answer the question with complete sentences.
Result: The molecule is a monocarboxylic acid anion that is the conjugate base of protoviolaceinic acid, resulting from the removal of the proton from the carboxy group. Major structure at pH 7.3. It is a conjugate base of a protoviolaceinic acid.
