Isoprene is an important C5 diolefin that can be polymerized to synthesize rubber, plastics and other synthetic materials as well as terpenes compounds. It has a typical conjugated double bond structure which is chemically active, it can also be used in the synthesis of fragrances, pesticides, drugs and other fine chemicals through various chemical reactions.
