2-Fluorothioanisole is widely used as an intermediate in the synthesis of agrochemicals, pharmaceuticals, and specialty chemicals. Its unique structure enables the introduction of fluorine and sulfur functionalities into target molecules, enhancing their bioactivity or material properties. Researchers employ it in palladium-catalyzed coupling reactions, such as Suzuki-Miyaura or Buchwald-Hartwig reactions, to construct complex aromatic systems. It also serves as a precursor for fluorinated thiophenes and other sulfur-containing heterocycles.
