Used as an intermediate in the synthesis of rubber chemicals, particularly as a precursor for sulfur-containing accelerators that enhance the vulcanization process. It contributes to improved cross-linking efficiency, leading to better heat resistance and mechanical properties in rubber products. Also employed in the development of certain corrosion inhibitors and stabilizers in polymer systems due to its thiazole and carboxylic functional groups. Its structure allows for metal chelation, making it useful in formulations where metal deactivation is required.
