  • What is p-toluenesulfonamide used for?
  • IDENTIFICATION AND USE: p-Toluenesulfonamide is a solid. It is used in organic synthesis, in plasticizers and resins, and as a fungicide and mildewicide in paints and coatings. It has been used as experimental therapy. HUMAN STUDIES: It is known as a common contact allergen.
  • What is p-toluene sulfonamide?
  • p-Toluenesulfonamide: Does not have an individual approval but may be used under an appropriate group standard o- and p-Toluene sulfonamide is an indirect food additive for use as a component of adhesives. /o- and p-Toluene sulfonamide/
  • How is p-toluenesulfonamide contaminated?
  • Limited monitoring data indicate that the general population may be exposed to p-toluenesulfonamide via ingestion of contaminated drinking water, and dermal contact with consumer products containing p-toluenesulfonamide (SRC).

  • How is p-toluenesulfonamide degraded?
  • Vapor-phase p-toluenesulfonamide is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals (SRC); the half-life for this reaction in air is estimated to be 13 days (SRC), calculated from its rate constant of 1.2X10-12 cu cm/molecule-sec at 25 °C (SRC) that was derived using a structure estimation method (2).
  • How many workers are exposed to p-toluenesulfonamide?
  • NIOSH (NOES Survey 1981-1983) has statistically estimated that 9,023 workers (1,223 of these are female) were potentially exposed to p-toluenesulfonamide in the US (1). Occupational exposure to p-toluenesulfonamide may occur through dermal contact with this compound at workplaces where p-toluenesulfonamide is produced or used.
  • Does p-toluenesulfonamide adsorb to suspended solids and sediments?
  • AQUATIC FATE: Based on a classification scheme (1), an estimated Koc value of 35 (SRC), determined from a log Kow of 0.82 (2) and a regression-derived equation (3), indicates that p-toluenesulfonamide is not expected to adsorb to suspended solids and sediment (SRC).
