Description and Uses
Indole-5-carboxylic acid is the suitable reagent used to study the intramolecular excited state proton transfer in indole-2-carboxylic acid and indole-5-carboxylic acid in various solvents in acidic, basic, and neutral media by steady state and time resolved fluorescence spectroscopy. It may be used in the electrochemical synthesis of poly(indole-5-carboxylic acid) (PICA) films.
