Chemical. CAS 99-98-9. Formula C8H12N2. MW 136.19. N,N-Dimethyl-p-phenylenediamine DMPD is a redox/oxidative stress indicator. It readily forms stable radical cations, involved in a variety of redox reactions. Has also been used to quantify labile sulfide in proteins, to detect sterolhydroperoxides, and for the measure of the antioxidant activity and used as an intermediate to produce dyes. DMPD is being explored for colorimetric detection of various analytes, especially in antioxidant assays. The principle of the assay is that at an acidic pH and in the presence of a suitable oxidant solution DMPD can form a stable and colored radical cation DMPD. Antioxidant compounds which are able to transfer a hydrogen atom to DMPD quench the color and produce a decoloration of the solution which is proportional to their amount. This reaction is rapid less than 10 min and the end point, which is stable, is taken as a measure of the antioxidative efficiency.
