N-Ethyl-O,P-Toluenesulfonamide is an organic sulfonamide compound derived from toluenesulfonic acid. Known for its excellent plasticizing properties, compatibility with a variety of polymers, and high thermal stability, it is widely used as both a primary plasticizer and performance additive to enhance flexibility, durability, and processability of resins.

This compound is valued in industries requiring heat-resistant, low-volatility, and high-performance plasticizers.
