China and India are the leading exporters of p-Toluenesulfonamide (CAS 70-55-3), collectively accounting for over 60% of global export value in 2023–2024, while the United States, Germany, and South Korea represent the largest importing markets. Import demand in the EU and North America has remained stable despite modest fluctuations in p-Toluenesulfonamide prices, with no significant shift in supplier concentration observed over the past two years.
p-Toluenesulfonamide is a white to off-white crystalline solid with a faint, characteristic odor and low volatility; it has a melting point of approximately 137–141 °C and is sparingly soluble in water. It is an aromatic organic compound classified as a sulfonamide and widely used as a chemical intermediate. Its primary industrial applications include synthesis of pharmaceuticals (e.g., sulfa drugs), agrochemicals (e.g., herbicides and plant growth regulators), dyes, and polymer additives such as plasticizers and crosslinking agents. It also serves as a catalyst or curing agent in coatings, adhesives, and epoxy resin systems.
1. It is used in the manufacture of dyes, synthetic resins, paints, disinfectants and wood processing brightener. 2. It is used for the manufacture of plasticizers, disinfectants; it can also be used for the production of synthetic resins, paints, and fluorescent dyes.3. It can be used as primary brightener in the bright nickel plating. It is sued for bright nickel plating for multilayer to obtain uniform bright coating. It has a commonly used amount of 0.2~0.3 g/L.4. It can be used as plasticizers, also used for synthesis of organics, resins and saccharin.
