application

5,6-Dihydroxyindole can be used as a building block to synthesize:
  • Eumelanin biopolymers via copolymerization reaction with 2-carboxy-5,6-dihydroxyindoles.
  • 4-[bis(1H-5,6-diacetoxyindol-2-yl)methyl]-1,2-diacetoxybenzene by reacting with 3,4-dihydroxybenzaldehyde.
  • Fluoride anion sensing acetylated trimer molecule via acid-catalyzed polymerization followed by acetylation reaction.
