General description

N,N-Dimethyl-p-phenylenediamine (DPD, DMPD) is an aromatic amine mainly used as an intermediate to produce dyes.[51] Its oxidation reaction with H2O2 in the presence of iron(III) catalyst has been used for the spectrophotometric detection of trace quantities of iron (III).[64] Cyclovoltammetric studies have been conducted to evaluate the electrochemical oxidation of DMPD at various pH. DMPD on oxidation under basic conditions has been reported to undergo hydrolytic decomposition.[65]

Application

N,N-Dimethyl-p-phenylenediamine may be used for the preparation of molecular compounds with tetracyano-p-quinodimethane (TCNQ). Polarized absorption spectra of these molecular compounds were investigated.[66]
