Di-p-tolyl sulfone is widely used as a high-temperature solvent in various industrial processes, particularly in the production of polymers and resins. Its stability at elevated temperatures makes it suitable for applications in the synthesis of polyethersulfones, which are essential in manufacturing high-performance plastics for aerospace, automotive, and electronics industries. Additionally, it serves as an intermediate in organic synthesis, contributing to the development of pharmaceuticals and agrochemicals. Its chemical resistance and thermal properties also make it valuable in coatings and adhesives, where durability under harsh conditions is required.
