1-CHLORO-2-METHYL-1-PROPENE Usage And Synthesis

Chemical Properties

Liquid.

Uses

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).

Uses

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

Definition

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

General Description

Clear dark yellow to pale orange liquid.

Air & Water Reactions

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

Reactivity Profile

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

Hazard

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

Fire Hazard

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

Carcinogenicity

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

Toxics Screening Level

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.
