Used primarily as a precursor in the synthesis of organic semiconductors and conductive materials. Its sulfur-rich structure makes it valuable in the preparation of tetrathiafulvalene (TTF) derivatives, which are key components in charge-transfer salts and molecular electronics. It also finds use in the development of organic superconductors and redox-active ligands for coordination chemistry. Additionally, it serves as a building block in materials science for creating extended π-conjugated systems with potential applications in thin-film transistors and photovoltaic devices.
