Used primarily as an intermediate in organic synthesis, this compound serves in the preparation of more complex aromatic and aliphatic systems. Its conjugated double bond structure makes it suitable for use in Heck reactions and other palladium-catalyzed coupling processes, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical manufacturing. It also finds use in research settings for studying stereochemical outcomes in addition reactions due to its defined E-configuration. Additionally, it can act as a model compound in kinetic studies involving radical reactions or isomerization processes.
