Task: Please create a text description for a molecule.
Molecule SMILES: O=C1C(c2[nH]c3ccc(S(=O)(=O)[O-])cc3c2O)=Nc2ccc(S(=O)(=O)[O-])cc21.[Na+].[Na+]
Constraint: Answer the question with full sentences.
Result: The molecule is an organic sodium salt resulting from the formal condensation of indigo carmine (acid form) with two equivalents of sodium hydroxide. It is an indicator at pH 11.5-14, changing from blue to yellow. It has a role as a food colouring, a histological dye and a two-colour indicator. It contains an indigo carmine(2-).
