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 methylthio groups allow for selective functionalization. Commonly employed in cross-coupling reactions, such as Suzuki or Ullmann reactions, to introduce aromatic sulfur motifs in target molecules. Also utilized in the preparation of liquid crystals and specialty polymers due to its stable aromatic backbone and polar substituents.
