• 2,5-Cyclohexadiene-1,4-dione, 2,6-bis(1,1-dimethylethyl)-: ACTIVE
• THE URINARY & FECAL EXCRETION OF 3 NEW METABOLITES OF BUTYLATED HYDROXYTOLUENE (BHT, 3,5-DI-TERT-BUTYL-4-HYDROXYTOLUENE) WERE REVEALED BY GAS CHROMATOGRAPHY AFTER IP ADMIN TO MALE WISTAR RATS. THE STRUCTURES OF THESE METABOLITES, 2,6-DI-TERT-BUTYL-P-BENZOQUINONE, 2,6-DI-TERT-BUTYLHYDROQUINONE, & 2,6-DI-TERT-BUTYL-4-((METHYLTHIO)METHYL)PHENOL WERE IDENTIFIED BY COMPARISON OF GAS CHROMATOGRAPHIC & MASS SPECTRAL DATA WITH THOSE OF AUTHENTIC SAMPLES.
• Quinones (ie, 6,12-dione) have been shown to undergo oxidation-reduction cycles involving quinone, hydroquinone, and molecular oxygen, resulting in the formation of oxygen radicals and semiquinone radicals. /Quinones/
