Used as a crosslinking agent in polymer chemistry, particularly in the vulcanization of rubber to improve heat resistance and mechanical strength. Acts as a sulfur-free curing agent, making it suitable for applications where low odor and reduced discoloration are important. Commonly applied in the production of specialty elastomers, sealants, and adhesives. Also serves as a reagent in organic synthesis for introducing sulfonyl groups or constructing heterocyclic compounds. Its stability under processing conditions makes it valuable in high-performance industrial materials.
