Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C 6 H 4 (OH) 2. It has two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also ... Product C was proposed to be 3-hydroxy-2-methyl-6-ethyl-hydroquinone (3-OH-MEHQ) , and the possible spontaneous oxidation product 3-hydroxy-2-methyl-6-ethyl-benzoquinone (3-OH-MEBQ), with a molecular ion of m/z 167 and the same MS/MS fragment ions, was also detected. In addition to 4-OH-MEA, MEHQ was detected in the MEA metabolites. I'm Aidan (or mehq, whatever skrub), I only get to go on a date after I write a poem page.
