Used primarily in organic electronics due to its conductive and electrochromic properties. It serves as a key intermediate in the synthesis of conductive polymers, especially in the development of poly(3,4-ethylenedioxythiophene) (PEDOT)-like materials. These materials are widely applied in flexible displays, smart windows, and anti-static coatings. Its carboxamide group allows for functionalization, improving solubility and enabling use in aqueous formulations for printed electronics. Also explored in biosensors and wearable devices due to its biocompatibility and stable electrochemical performance.
