Used primarily in the synthesis of dithiol-containing compounds for applications in polymer chemistry, particularly as a crosslinking agent in specialty resins and coatings. It serves as a building block in the preparation of metal chelating agents due to its ability to form stable complexes with heavy metal ions, useful in wastewater treatment and metal recovery processes. Also employed in the development of functional monomers for conductive polymers and in the formulation of certain cosmetic ingredients, where it contributes to modifying rheological properties and enhancing stability. Its bifunctional thiol groups enable participation in thiol-ene reactions, making it valuable in photo-curable systems and advanced material synthesis.
