Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for functionalization at both the pyridine ring and the thioether linkage, making it valuable in the development of ligands for catalysis and in the synthesis of bioactive molecules. Commonly employed in the formation of chelating agents due to the nitrogen and sulfur donor atoms, which can coordinate to metal centers. Also finds use in the production of specialty chemicals where a sulfur-linked hydroxyethyl pyridine moiety is required.
