INDOLE-2,3-DIONE(91-56-5) is an indole derivative. In 1841, Erdman and Laurent first obtained the compound as a product from the oxidation of indigo dye by nitric acid and chromic acids. The compound is found in many plants.Schiff bases of INDOLE-2,3-DIONE are investigated for their pharmaceutical properties.It was observed that it forms a blue dye if it is mixed with sulfuric acid and crude benzene. The formation of the blue indophenin was long believed to be a reaction with benzene. Victor Meyer was able to isolate the substance responsible for this reaction from benzene. This new heterocyclic compound was thiophene.
