Isoprene is a colorless, volatile organic compound with the chemical formula C5H8. It is a natural product found in various plants, particularly in the rubber tree, where it serves as a building block for the production of natural rubber. Isoprene is also used in the manufacture of synthetic rubber and other polymers. In addition to its industrial applications, isoprene plays a role in the atmosphere as a biogenic volatile organic compound. It can contribute to the formation of ozone and aerosols, impacting air quality and climate. Understanding isoprene's behavior is important for environmental science and industrial chemistry.
