Application

N,N-Dimethyl-p-phenylenediamine sulfate salt was used:
  • to investigate the role of H2S in cardioprotection induced by ischemic preconditioning in rat heart
  • in spectrophotometric determination of gold(III) in gold-pharmaceuticals such as sodium aurothimaleate and auranofin
  • to investigate colonic tissue H2S production using the acetate trapping assay system
