Germany and the United States are the leading exporters of Methylcyclopentadiene dimer (CAS 26472-00-4), accounting for the largest share of global shipments, while China, South Korea, and India represent the principal importers. Methylcyclopentadiene dimer prices have remained relatively stable amid steady cross-border flows over the past two years. Export volumes from the EU and U.S. have held steady since 2023, while imports into Asia—particularly by South Korea and India—showed modest growth, reflecting continued demand in specialty chemical synthesis.
Methylcyclopentadiene dimer is a colorless to pale yellow liquid at room temperature, with a characteristic pungent odor and moderate volatility. It is a cyclic diene dimer classified as an organic chemical intermediate, derived from the Diels–Alder reaction of methylcyclopentadiene monomers. Industrially, it serves primarily as a precursor to methylcyclopentadienyl metal complexes—most notably methylcyclopentadienyl manganese tricarbonyl (MMT), an octane-enhancing fuel additive—and as a ligand source in organometallic synthesis. Its principal applications are in specialty fuels and catalysis, with limited use in research-scale synthesis of transition metal catalysts for polymerization and fine chemical manufacturing.
