Dicyclopentadiene, often abbreviated as DCPD, is a cyclic hydrocarbon with the chemical formula C10H12. It is a dimer of cyclopentadiene, formed through a Diels-Alder reaction. At room temperature, DCPD is a white crystalline solid with a camphor-like odor. It is soluble in many organic solvents but insoluble in water.

DCPD is primarily produced as a byproduct of coal tar distillation and petroleum cracking. Its reactivity stems from the presence of strained double bonds, making it a versatile building block in organic synthesis. The most significant industrial application of DCPD is in the production of resins. Unsaturated polyester resins, hydrocarbon resins, and epoxy resins derived from DCPD are used in a wide range of products including coatings, adhesives, printing inks, and molding compounds.

Another important use of DCPD is in the synthesis of various chemicals. It serves as a precursor for the production of pesticides, flame retardants, and specialty polymers. Its ability to undergo various addition and polymerization reactions makes it valuable for creating complex organic molecules. The handling of DCPD requires care due to its flammability and potential for skin and eye irritation.
