Used primarily as a cross-linking agent in polymer chemistry, it enhances the mechanical properties and thermal stability of materials. It is also employed in the synthesis of specialty polymers and resins, particularly those requiring high strength and durability. In the pharmaceutical industry, it serves as an intermediate in the production of certain drugs, contributing to the development of active pharmaceutical ingredients. Additionally, it finds application in the creation of advanced adhesives and coatings, where its disulfide bonds provide improved adhesion and resistance to environmental factors.
