Used in organic synthesis as an intermediate for the production of pharmaceuticals and agrochemicals. Its sulfonyl and nitrile functional groups make it valuable for constructing complex molecules. It is also employed in the development of dyes and pigments due to its ability to form stable aromatic structures. Additionally, it serves as a precursor in the creation of polymers and resins, enhancing their thermal and chemical stability. Its application extends to research laboratories for studying reaction mechanisms involving sulfonyl and nitrile groups.
