Used primarily as a vulcanization accelerator in the rubber industry, especially in the production of tires and industrial rubber goods. It helps improve the efficiency of the sulfur curing process, leading to enhanced mechanical properties such as tensile strength and elasticity. Also acts as a lubricant additive, providing anti-wear and extreme pressure performance in engine oils and metalworking fluids. Its thermal stability makes it suitable for high-temperature processing applications. Additionally, it serves as an intermediate in the synthesis of other organosulfur compounds used in agrochemicals and pharmaceuticals.
