Description

General description

N,N-Dimethyl-p-phenylenediamine dihydrochloride is an azoreduction product of acid orange 52 (AO52). 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).

Caution

May discolor to red on storage.
