p-toluenesulfonamide

p-Toluenesulfonamide (CAS 70-55-3), also known as p-tosylamide, is a sulfonamide compound used primarily as a biocide and plasticizer intermediate.

Where is p-toluenesulfonamide used?

• Water treatment: controls microbial growth in cooling towers
• Industrial process water and recirculating systems: antimicrobial agent where biological fouling is a persistent operational problem
• Textile and leather: preservative in finishing baths
• Coatings: extends the working life of aqueous preparations
• Plastics: plasticizer or modifier intermediate in resin production
• Paper manufacturing incorporates it into process water treatment programs to suppress bacterial and fungal contamination during pulp processing.

Commercial specifications

• Purity typically 99% or above for industrial applications
• Packaging in bags and drums suited to bulk industrial procurement
