Furan has an important biological properties and pharmacological activity. Its iodinated lipophilic derivative is widely used in the treatment of ventricular and arterial fibrillation. Its derivatives are used as inhibitors of biofilm formation for several bacterial species, as well as possess quorum-sensing inhibitory activities. 2-methylfuran and 2,5-dimethylfuran are used as lignocellulosic biofuels. Its resin is used to stop sand production in underground gas storage wells. It undergo Diels-Alder reaction with arynes to give derivatives of dihydronaphthalenes which are useful intermediates in synthesis of other polycyclic aromatic compounds.
