1. In the bone marrow, MPO converts these polyphenols to benzoquinones . 2. NQ01 metabolizes benzoquinone toward polyphenols ( counteracting the effect of MPO ). 3. Benzoquinone reacts with acetic anhydride and sulfuric acid to give the triacetate of hydroxyquinol.4. The oxidation will lead to a benzoquinone like motif-- a Michael acceptor. 5. Several isomeric naphthoquinones are known, notably benzoquinone . 6. 1, 4-Benzoquinone is used in the synthesis of Bromadol and related analogs. 7. For the latter, benzoquinone is suggested. 8. Also known as tetrachloro-1, 4-benzoquinone , it is a yellow solid. 9. Like the parent benzoquinone , chloranil is a planar molecule that functions as a mild oxidant. 10. The unqualified term " hydroxybenzoquinone " usually means a derivative of 1, 4-benzoquinone .
