Description

CAS: 106-51-4 | C6H4O2 | 108.096 g/mol

p-Benzoquinone is used as a dienophile in Diels-Alder cycloadditions to prepare naphthoquinones and 1,4-phenanthrenediones. It acts as a dehydrogenation reagent and an oxidizer in synthetic organic chemistry. In the Thiele-Winter reaction, it is involved in the preparation of triacetate of hydroxyquinol by reacting with acetic anhydride and sulfuric acid. It is also used in the synthesis of bromadol and to suppress double- bond migration during olefin metathesis reactions. It is used as a precursor to hydroquinone which finds application in photography and as a reducing agent and an antioxidant in rubber production.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
