Used primarily as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its unique structure, featuring both chloro and iodo substituents, makes it valuable for constructing complex molecules through cross-coupling reactions. It is also employed in the synthesis of sulfur-containing compounds, which are often explored for their biological activity. Additionally, it serves as a building block in the preparation of ligands for catalytic systems, aiding in the development of new materials and chemical processes.
