Used as a crosslinking agent in polymer chemistry, particularly in the vulcanization of rubber and in the production of heat-resistant elastomers. Enhances thermal stability and mechanical strength of polymers. Commonly applied in the synthesis of high-performance resins and composite materials for aerospace and automotive industries. Also utilized in specialty adhesives and coatings where durability under high temperature is required. Shows utility in modifying protein structures in biochemical research due to its ability to react with thiol and amine groups.
