2-Chlorothioanisole serves as a key intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty chemicals. It is commonly employed in Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions due to its reactive chlorine and sulfur moieties. Researchers also utilize it in the development of sulfur-containing ligands for catalysis and as a precursor for bioactive molecules.
