2-Methyl-2-butene,2m2b,2-methylbut-2-ene,alsobeta-isoamyleneis analkenehydrocarbonwith the molecular formula C5H10.
Used as a free radical scavenger intrichloromethane(chloroform) anddichloromethane(methylene chloride). It is also used to scavengehypochlorous acid(HOCl) in thePinnick oxidation.
John Snow,the English physician, experimented with it in the 1840s as an anesthetic, but stopped using it for unknown reasons.[4]
