Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of herbicides and fungicides. Its thiol group allows for easy functionalization, making it valuable in building complex organic molecules. Commonly employed in cross-coupling reactions and nucleophilic substitutions to introduce aromatic rings with specific halogen patterns. Also utilized in the preparation of specialty polymers and ligands for catalysis due to its electron-withdrawing substituents and reactive sulfur center.
