Description générale

o-Toluenesulfonamide is a major impurity in artificial sweetening substances containing saccharin. Determination of o-toluenesulfonamide in saccharin and saccharin sodium by reversed-phase HPLC method has been reported.

Application

  • Dynamic ligand reactivity in a rhodium pincer complex.: Discusses the role of o-toluenesulfonamide as a ligand in advanced chemical syntheses, demonstrating its utility in creating reactive intermediates for catalytic processes (Tang et al., 2015).
  • Reaction of arylium ions with the collision gas N2 in electrospray ionization mass spectrometry.: Highlights the use of o-toluenesulfonamide in mass spectrometry studies to understand ionization mechanisms, aiding in the identification of complex chemical structures (Liang et al., 2015).
  • Benzosulfonamides in wastewater: method development, occurrence and removal efficiencies.: Focuses on the development of methods to detect and remove o-toluenesulfonamide from wastewater, emphasizing its prevalence and the challenges associated with its elimination (Ajibola et al., 2015).
