Dibutyl fumarate

Dibutyl fumarate (CAS No. 105-75-9), with the molecular formula C12H20O4, is an unsaturated diester derived from fumaric acid and n-butanol. It appears as a colorless to pale yellow liquid with a faint, characteristic ester-like odor. Its chemical structure contains an electron-deficient carbon-carbon double bond (trans-configured), which makes it reactive and capable of undergoing copolymerization reactions. It is widely used as a reactive monomer and plasticizer.
