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’s used as a precursor to hydroquinone which finds application in photography and as a reducing agent and an antioxidant in rubber production. Light sensitive; store in cool place ; incompatible and reacts violently with strong oxidizing agents This product is for research use only, is not to be used for therapeutic; not intended for animal or human or diagnostic or therapeutic use , and cannot be sold to patients. Special for chemical transport (according to IATA / ADR / ECHA-REACH rules / int.l laws) . According to U.S. / E.U. Pharmacopoeia, Echa-Reach, UNI EN ISO 14001, G.M.P., M.S.D.S., etc... |
