 Diphenylmercury (CAS NO.587-85-9) is also called 4-16-00-01702 (Beilstein Handbook Reference); AI3-17856 ; BRN 0637234 ; Benzene, mercuriodi- ; Difenylrtut [Czech] ; NSC 23990 ;Mercury, diphenyl- . Diphenylmercury (CAS NO.587-85-9) is a colourless, crystalline organomercury compound. Diphenylmercury (CAS NO.587-85-9) is a kind of pesticides. It is high toxic. It is flammable by fire. It will decomposit toxic mercury-containing compounds fumes by high heat. So the storage environment should be ventilate, low-temperature and dry. Keep Diphenylmercury (CAS NO.587-85-9) separate from oxidants, food additives and acids.
