Isoprene

Isoprene (/aɪsəpriːn/), also known as 2-methyl-1,3-butadiene is a common organic compound with the formula CH2=C(CH3)−CH=CH2. It is a colorless volatile liquid that is produced by many plants. Its polymers are the main component of natural rubber.

Etymology

The word "isoprene" is derived from the Greek words "iso" meaning "equal" and "prene" which is short for "polyterpene", indicating its origin and main applications.

Structure and Synthesis

Isoprene is a five-carbon compound that is emitted from various plants. Its structure consists of four carbon-carbon double bonds and a methyl group. The synthesis of isoprene in plants is thought to proceed via the mevalonate pathway.

Uses

Isoprene is primarily used in the production of synthetic rubber through a process called polymerization. It is also used in the manufacture of certain adhesives, resins, and paints.

Health Effects

Exposure to isoprene can cause irritation to the eyes, skin, and respiratory tract. It is also classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC).
