| | trans-2,3-Dibromo-2-butene-1,4-diol Usage And Synthesis |
| Chemical Properties | white crystalline powder | | General Description | Crystals or white powder. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | A halogenated alkene and alcohol. The unsaturated aliphatic hydrocarbons are generally much more reactive than the alkanes, which are saturated aliphatic hydrocarbons. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. | | Fire Hazard | Flash point data for trans-2,3-Dibromo-2-butene-1,4-diol are not available, however trans-2,3-Dibromo-2-butene-1,4-diol is probably combustible. |
