pale yellow to brown crystals or powder
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.
ChEBI: Para-Benzoquinone dioxime is a quinone imine.
Pale yellow crystals or brown powder.
1,4-Benzoquinone dioxime is incompatible with strong oxidizers and strong acids.
Flash point data for 1,4-Benzoquinone dioxime are not available; however, 1,4-Benzoquinone dioxime is probably combustible.
Flammability and Explosibility
Flammable
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.
Moderately toxic by
ingestion. Questionable carcinogen with
experimental neoplastigenic and tumorigenic
data. Mutation data reported. When heated
to decomposition it emits toxic fumes of
NOx,.
