Description

General description

N,N-Dimethyl-p-phenylenediamine dihydrochloride is an azoreduction product of acid orange 52 (AO52).[1] It is useful in the oxidase test which differentiates bacteria based on their ability to utilise the dye.

Application

N,N-Dimethyl-p-phenylenediamine dihydrochloride has been used to determine the plasma oxidant capacity in terms of plasma ferric equivalent oxidative potential (PFEOP).
