  • What happens if DMPD is oxidized?
  • When the compound N,N-dimethyl-ρ-phenylenediamine (DMPD) is in the presence of a suitable oxidant solution, a colored radical cation is formed (DMPD•+). Antioxidant compounds, which can transfer a hydrogen atom to DMPD•+, cause a decoloration of the solution.
  • What causes a Decoloration of DMPD?
  • Antioxidant compounds, which can transfer a hydrogen atom to DMPD•+, cause a decoloration of the solution. In our assay a solution of DMPD at an acidic pH and in the presence of a suitable oxidant solution, can form a stable and colored radical cation (DMPD•+) which shows a maximum of absorbance at 553 nm.
