Used as a ligand in coordination chemistry, particularly in the formation of metal complexes with transition metals, due to the presence of nitrogen atoms in the pyridine rings and the disulfide bridge. The compound facilitates the stabilization of metal centers in catalytic systems, making it useful in catalysis research. Its disulfide bond can participate in redox-active processes, which is beneficial in studies related to electron transfer reactions. Additionally, it serves as a building block in the synthesis of more complex heterocyclic compounds with potential biological activity. Applications extend to materials science, where such sulfur- and nitrogen-containing molecules contribute to the development of functional organic materials.
