| Hazard Information | Back Directory | [General Description]
Colorless liquid. | [Reactivity Profile]
An unsaturated aliphatic/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. | [Air & Water Reactions]

2-Methyl-3-buten-2-ol may be used as an analytical reference standard for the determination of the analyte in Humulus Lupulus L. (Hop) and pine-mushroom extracts by chromatography techniques. | [Uses]
2-Methyl-3-buten-2-ol was used to study the kinetics of the gas-phase reaction of OH radicals with 3-methyl-2-butenal. | [Definition]
ChEBI: 3-hydroxy-3-methylbut-1-ene is a tertiary alcohol that is 3-methylbut-1-ene carrying a hydroxy substituent at position 3. It has a role as a fragrance, a pheromone, a plant metabolite and an animal metabolite. It is a tertiary alcohol and an olefinic compound. It derives from a hydride of a 3-methylbut-1-ene. |
