1-Chloro-2-methyl-1-propene

Liquid.

Dimethylvinyl chloride is not used commercially, but is used for research purposes. It has been used in organic syntheses and as a chemical intermediate for the production of isobutylene compounds for laboratory use (IARC 1995, HSDB 2009).

1-Chloro-2-methylpropene was used to study multiple infrared photon excitation of α-chloro olefins.

ChEBI: 1-Chloro-2-methylpropene is an organochlorine compound.

Clear dark yellow to pale orange liquid.

Highly flammable. May be sensitive to prolonged exposure to air and light. Slightly soluble in water.

1-CHLORO-2-METHYL-1-PROPENE is incompatible with strong oxidizing agents and strong bases.

Carcinogen; neoplastigen; moderately toxic; local irritant, and narcotic.

1-CHLORO-2-METHYL-1-PROPENE is flammable.

Dimethylvinyl chloride is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.

The unit risk value of 1.18 x 10-5, estimated from the incidence of forestomach neoplasms in male mice, is used to estimate the risk to human populations exposed to dimethylvinyl chloride. Using this unit risk value, the concentration of dimethylvinyl chloride in air resulting in an increased cancer risk of one in one million (1 x 10-6) is 0.008 μg/m3.
