What is the mechanism of oxidation of phenol to benzoquinone? (stackexchange.com)
Cells were exposed to benzene, phenol, catechol, hydroquinone, p-benzoquinone, or 1,2,4-benzenetriol over the range of 1.0 X 10(-7) to 1.0 X 10(-2) M for 30 min, and the rate of DNA synthesis was measured at various times after chemical washout. (aspetjournals.org)
Benzoquinone was the most potent inhibitor of DNA synthesis, followed by hydroquinone, benzenetriol, catechol, and phenol with ED50 values of 5 X 10(-6), 1 X 10(-5), 1.8 X 10(-4), 2.5 X 10(-4), and 8.0 X 10(-4), respectively. (aspetjournals.org)
It is one of the two isomers of quinone , the other being 1,4-benzoquinone . (alchetron.com)
To handle these two issues, we have synthesized a novel organic cathode material by anchoring a quinone compound, 2,3-dicyano- p -benzoquinone (DCBQ) with a high redox potential of 3.37 V vs. Li/Li + , onto carbon nanotubes (CNTs) (CNTs-DCBQ) through a facile ''grafting to'' method. (osti.gov)
Benzene1
Certain benzene metabolites, including benzoquinone (BQ), are genotoxic and mutagenic. (rti.org)
Hydroquinone1
Hydroquinone undergoes oxidation to benzoquinone under mild conditions. (sciencemadness.org)
Acetaminophen3
In this study, the common analgesic, acetaminophen, was chlorinated with sodium hypochlorite to determine the effects of pH and chlorine-to-pharmaceutical molar ratios on the degradation of acetaminophen and the formation of the toxic byproduct 1,4-benzoquinone. (iwaponline.com)
The degradation of acetaminophen and the formation of 1,4-benzoquinone were monitored using liquid chromatography tandem mass spectrometry (LC/MS/MS). Results indicate that acetaminophen is most reactive with free chlorine at pH 9.0 and least reactive at pH 6.0. (iwaponline.com)
The formation of 1,4-benzoquinone was also affected by pH and its concentration reached a maximum of 68.7% of the initial acetaminophen concentration when the pH was at 6.0, the molar ratio at 1,275, and after a contact time of 30 minutes. (iwaponline.com)
Derivatives2

Catechol1
A strain of the bacterium Pseudomonas mendocina metabolises benzoic acid , yielding 1,2-benzoquinone via catechol . (alchetron.com)
Metabolites1
Tyrosine and p -benzoquinone were the dominant metabolites in all of the secretions, accounting for approximately 11.29% of emissions, with the portion in the solid phase being generally higher than that in the liquid phase. (frontiersin.org)
Analysis2
K + . In order to know more about the chemical structure of the alkali salts, the lithium, sodium and potassium salts of bistriazole- p -benzoquinone were crystallized and their structure could be revealed by single crystal X-ray analysis. (rsc.org)
Therefore, metabolome analysis suggested that p -benzoquinone, which may potentially be developed to be a valuable marker for determining external immunity, was considered to be the main substance responsible for external immune functions. (frontiersin.org)
Found2

Acetic acid3
The effects of ascorbic acid on the excretion of homogentisic acid and its derivative benzoquinone acetic acid were studied in two adults and three infants. (nih.gov)
The administration of relatively large amounts of ascorbic acid to the adults was followed by a disappearance of benzoquinone acetic acid from the urine, whereas the level of excretion of homogentisic acid did not change. (nih.gov)
Homogentisic acid is subsequently converted to benzoquinone acetic acid and spontaneously polymerized. (medscape.com)
