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.

After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals
