General description

p-Toluidine undergoes oxidative coupling reaction with catecholamine to form an orange water-soluble dye during flow injection-spectrophotometric determination of catecholamine drugs.

Application

p-Toluidine has been used in preparation of:
  • aromatic azo compounds
  • bidentate Schiff base ligands via condensation with salicylaldehyde
