Piperylene, also known as 1,3-pentadiene, is a colorless liquid hydrocarbon with a chemical formula of C5H6. It is an unsaturated compound, meaning it contains double bonds between carbon atoms. Piperylene is primarily used in the production of synthetic rubber and as a chemical intermediate in various industrial processes. This compound is typically obtained from the cracking of petroleum and is a component of some natural gas streams. Due to its reactivity, piperylene can undergo polymerization, leading to the formation of larger molecules. Its applications extend to the manufacture of resins and other chemical products.
