Piperylene or 1,3-pentadiene is a volatile, flammable hydrocarbon consisting of a five carbon chain with two double bonds separated by one single bond. It is one of the five positional isomers of pentadiene.

Piperylene is obtained as a byproduct of ethylene production from crude oil, combustion of biomass, waste incineration and exhaust gases. It is used as a monomer in the manufacture of plastics, adhesives and resins.^[2] At standard conditions, piperylene is a colorless liquid.^[3] Upon release into the aquatic environment it is expected to adsorb to suspended particulate matter (SPM) based on its estimated KOC value.

The alternating double and single carbon-carbon bonds form a conjugated system.
