Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of sulfur-containing active ingredients. It serves as a sulfurating agent in organic transformations, enabling the introduction of disulfide bonds in complex molecules. Also applied in the preparation of rubber chemicals and vulcanization accelerators, enhancing the cross-linking process in rubber manufacturing. Its chlorinated aromatic structure makes it useful in certain coupling reactions and as a building block in specialty chemicals requiring thermal and chemical stability.
