Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. It serves as a building block in organic reactions where the chloro and thioether functionalities allow for selective transformations. Commonly employed in cross-coupling reactions, such as Suzuki or Ullmann reactions, to introduce aryl thioether moieties in target molecules. Also utilized in the preparation of functionalized aromatic compounds for research in medicinal chemistry.
