Description

General description

N,N-Dimethyl-p-phenylenediamine (DPD, DMPD) is an aromatic amine mainly used as an intermediate to produce dyes. 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). 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.

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.
