Phenanthrenequinone
Phenanthrenedione is a quinone derivative of a polycyclic [aromatic hydrocarbon]. It is an orange, water-insoluble solid.
Laboratory synthesis and use
It has been prepared by oxidation of phenanthrene with chromic acid.It is used as an artificial mediator for electron acceptor/donor in Mo/W containing formate dehydrogenase reduction of carbon dioxide to formate and vice versa. It is a better electron acceptor than the natural nicotinamide adenine dinucleotide.
Safety
It is cytotoxic and potentially mutagenic.Phenanthrenequinone is one of many contributors to harmful particulate emissions from diesel motor vehicles.
