CAS 78-79-5: Isoprene

Description: Isoprene, with the CAS number 78-79-5, is a colorless, volatile liquid that is classified as a diene due to its two conjugated double bonds. Its molecular formula is C5H8, and it has a characteristic sweet odor. Isoprene is highly flammable and has a low boiling point, making it easily vaporized at room temperature. It is primarily used as a building block in the production of synthetic rubber, particularly polyisoprene, which mimics the properties of natural rubber. Isoprene is also a natural product, emitted by various plants, and plays a role in atmospheric chemistry. In terms of reactivity, isoprene can undergo polymerization, oxidation, and various addition reactions, making it a versatile compound in organic synthesis. Safety precautions are essential when handling isoprene due to its flammability and potential health hazards, including respiratory irritation and central nervous system effects upon exposure. Overall, isoprene is an important industrial chemical with significant applications in materials science and environmental chemistry.
