Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. Its nitrile and sulfonyl functional groups make it valuable in building complex organic molecules, especially in the development of herbicides and plant growth regulators. It participates in coupling reactions and can serve as a precursor for sulfur-containing bioactive compounds. Its tert-butyl sulfonyl group provides steric bulk and stability, enhancing selectivity in reaction pathways. Commonly employed in research settings for designing novel sulfone-based active ingredients.
