Uses

N,N-Dimethyl-1,4-phenylenediamine oxalate (N,N-dimethyl-p-phenylenediamine hemioxalate salt, DPD) was used as reagent in a study to evaluate the catalytic effects of elemental sulfur nanoparticles on CrVI reduction. It was also used to study the transformation of trichloroethene (TCE), caused by heating contaminated soil and groundwater samples.
