Use

Tetrahydrofuran (THF) is an organic, polar, water-miscible, cyclic ether and aprotic solvent with low viscosity. It is a chemical intermediate used in the manufacture of polymers as well as agricultural, pharmaceutical, and commodity chemicals.BASF and Dairen Chemical together accounted for approximately half of the share of the THF market in 2016. BASF is the leader in the THF market.
