General description

The electrochemical behaviour of p-benzoquinone dioxime on modified Pt electrodes has been studied in aqueous HClO4 solutions by employing cyclic voltammetric and rotating-disc or ring-disc techniques.

Application

p-Benzoquinone dioxime was used in oxidative regeneration of a variety of carbonyl compounds from their oximes using superoxide ion generated in situ by the phase transfer reaction between potassium superoxide and 18-crown-6.

Biochem/physiol Actions

p-Benzoquinone dioxime is sex-specific rat carcinogen inducing tumours of the urinary bladder in female rats and is a direct-acting mutagen in Salmonella typhimurium TA982.
