Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized aromatic compounds. It serves in the development of pharmaceuticals and agrochemicals due to the reactivity of the disulfide bond and the presence of bromine as a handle for cross-coupling reactions. Also employed in the synthesis of conductive polymers and organic electronic materials where controlled sulfur incorporation is required. Its stability and reactivity profile make it suitable for use in radical reactions and as a building block in materials science.
