N,N-Dibutylbenzenesulfonamide is primarily used as a plasticizer in the manufacturing of polymers and resins. It enhances the flexibility and durability of plastic products, making it valuable in the production of items such as PVC films, cables, and synthetic leather. Additionally, it serves as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its solvency properties also make it useful in industrial cleaning formulations and coatings.
