Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and plant growth regulators. It serves as a sulfination reagent in organic transformations, enabling the introduction of sulfinyl groups into aromatic systems. Its chloropyridine backbone makes it valuable in constructing bioactive molecules with enhanced selectivity and stability. Also employed in the development of ligands for catalytic processes and in the preparation of functional materials requiring specific electronic properties.
