Widely used in organic synthesis, particularly as a key reagent in the preparation of dithiolethiones and related sulfur-containing heterocycles. It serves as a building block in the development of materials with nonlinear optical properties due to its extended π-conjugated system and electron-rich sulfur atoms. Commonly employed in the synthesis of tetrathiafulvalene (TTF) derivatives, which are essential in the field of organic conductors and molecular electronics. Its ability to undergo oxidative coupling makes it valuable in creating charge-transfer complexes and organic superconductors. Also investigated for use in electroactive polymers and thin-film semiconductors for optoelectronic devices. Shows potential in medicinal chemistry due to the biological activity associated with dithiolethione scaffolds, including antioxidant and chemopreventive properties.
