Isoprene is a hemiterpene with the formula CH2=C(CH3)CH=CH2; the monomer of natural rubber and a common structure motif to the isoprenoids, a large class of other naturally occurring compounds. It has a role as a plant metabolite. Isoprene, stabilized appears as a clear colorless liquid with a petroleum-like odor. Density 5.7 lb / gal. Flash point -65 °F.
