Used as a multifunctional sulfur donor in the synthesis of advanced rubber additives, particularly in the development of high-performance vulcanization systems. Its structure enables efficient cross-linking in elastomers, improving heat resistance, mechanical strength, and durability of rubber products. Commonly applied in specialty tires, industrial hoses, and seals where long-term stability under thermal stress is critical. Also investigated as a precursor in the preparation of metal chelating agents and lubricant modifiers due to its high sulfur content and thermal stability.
