Used as a key intermediate in the synthesis of conductive polymers and organic semiconductors due to its ability to form disulfide bridges and conjugated structures. Its aldehyde functional groups allow for further chemical modifications, making it suitable for building covalent organic frameworks (COFs) used in sensing and catalysis. Also employed in the development of redox-responsive materials for drug delivery systems, where the disulfide bond can be cleaved under reducing conditions. Shows potential in electrochemical applications, including biosensors and energy storage devices, owing to its electron-withdrawing properties and structural stability.
