Colorless, extremely volatile liquid or gas; disagreeable odor.Soluble in alcohol; insoluble in water.??? ??
Colorless, flammable liquid or gas with a disagreeable odor??
3-Methyl-1-butene has been used in asymmetric total synthesis of ()-Linderol A, a potent inhibitor of melanin biosynthesis of cultured B-16 melanoma cells.??
ChEBI: An alkene that is but-1-ene carrying a methyl substituent at position 3.?? ??
A colorless volatile liquid with a disagreeable odor. Insoluble in water and less dense than water. Vapors heavier than air. Flash point below 0°F. Used to make other chemicals.??? ?? ??
Highly flammable. Insoluble in water.?? ???
3-Methyl-1-butene may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. In the presence of various catalysts (such as acids) or initiators, may undergo exothermic addition polymerization reactions.???
Highly flammable, dangerous fire and explosion risk, explosive limits 1.6–9.1%.????
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.Safety Profile
Very dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. To fight fire, use alcohol foam, mist, spray, dry chemical, CO2. When heated to decomposition it emits acrid smoke and irritating fumes. See also 2-METHYL-1 BUTENE.????
Photolytic. The following rate constants were reported for the reaction of 3-methyl-1-butene and OH radicals in the atmosphere: 3.0 x 10-11 cm3/moleculesec (Atkinson et al., 1979); 6.07 to 9.01 x 10-11 cm3/moleculesec (Atkinson, 1985); 3.18 x 10-11 cm3/moleculesec (Atkinson, 1990).Chemical/Physical. Complete combustion in air yields carbon dioxide and water.
