General description

Bis(2,4-dinitrophenyl) oxalate (DNPO) is a chemiluminescence reagent. Chemiluminescence produced in the oxidation of DNPO by hydrogen peroxide in the presence of a polycyclic aromatic hydrocarbon was monitored by spectroscopic methods. The kinetics of the imidazole-catalyzed decomposition of DNPO was investigated by the stopped-flow technique.

Application

Bis(2,4-dinitrophenyl) oxalate was used in detection of fluorescent compound dansylalanine in buffer solution by flow injection analysis.
