Anwendung

Methyl-p-benzoquinone (MBQ) can be used as a coating that forms an interface between the electrode and lithium (Li) electrolyte for the fabrication of redox flow batteries. It can be reduced during positive electrospray ionization mass spectroscopy (ESI MS) and can be potentially used during corona discharge.

The defensive glands of beetles, Tenebrio molitor, infected with metacestodes (cysticercoids) of Hymenolepis diminuta are everted less frequently upon stimulation, and contain less toluquinone (methylbenzoquinone) and m-cresol, than glands of uninfected controls. These differences, as shown in predation trials with

Unexpected reduction of iminoquinone (IQ) and quinone derivatives was first reported during positive electrospray ionization mass spectrometry. Upon increasing spray voltage, the intensities of IQ and quinone derivatives decreased drastically, accompanying the increase of the intensities of the reduction products

Inactivation kinetics of pyruvate decarboxylase under joint action of substrate and substituted quinones in aqueous solutions which contain 1.0-13.5 vol.% of methyl alcohol has been investigated. The observed inactivation rate constant of pyruvate decarboxylase sharply decreases with the increase of
