| | 1-Bromo-2-methylpropane Usage And Synthesis |
| Chemical Properties | CLEAR LIQUID | | Uses | 1-Bromo-2-methylpropane is used as a synthetic reagent for the preparation of 1-ethyl-1,3-isobutylimidazolium bromide by reaction with 1-ethylimidazole. | | Safety Profile | Questionable
carcinogen with experimental neoplastigenic
data. Moderately toxic by intraperitoneal
route. A dangerous fire hazard when
exposed to heat or flame. When heated to
decomposition it emits toxic fumes of Br-.
