Used as a crosslinking agent in polymer chemistry, particularly in the development of specialty rubbers and elastomers. It enables controlled vulcanization, improving heat resistance and mechanical strength of the final product. Also employed in the synthesis of functional materials where selective sulfur-based linkages are required. Its bifunctional structure allows for bridging reactive sites in macromolecules, making it valuable in modifying polymer networks for industrial coatings and adhesives. Additionally, it is utilized in biochemical research to bind with proteins or biomolecules, facilitating the study of protein structure and function.
