Used primarily in the rubber industry as a sulfur-containing accelerator in vulcanization processes, enhancing the cross-linking of rubber polymers for improved elasticity and durability. It is especially effective in the production of tires and industrial rubber goods where heat resistance and mechanical strength are critical. Its mercapto and ethoxy functional groups contribute to better dispersion and scorch safety during processing. Also finds use in some corrosion inhibitor formulations and as an intermediate in the synthesis of agrochemicals and pharmaceuticals due to its reactive heterocyclic structure.
