p-Benzoquinone, 99.9%, Certified®

Description

SUITABILITY
For research and development, not for animal, human, diagnostic, or therapeutic use.
APPLICATIONS
Is a cyclic conjugated diketone. Its high-resolution photoelectron spectrum has been reported. The visible and near ultraviolet spectra of PBQ have been recorded and analyzed. Its addition as coagent has been reported to enhance the crosslinking rate of polypropylene initiated by the pyrolysis of peroxides. Its impact on hemoglobin (Hb) has been investigated based on immunoblots and mass spectral analysis of a smoker′s blood. Free radical inhibitor. May be used to form benzofuranone derivatives on reacting with anilides of β-aminocrotonic acids via Nenitzescu reaction.
Dienophile employed in Diels-Alder cycloadditions to form naphthoquinones, and 1,4-phenanthrenediones.
Oxidant used in first step of greener amine synthesis from terminal olefins by Wacker oxidation followed by transfer hydrogenation of the resultant imine. 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.
