Product Description

Product Description

Tetrahydrofuran (THF, oxolane) is a versatile solvent used in laboratory organic synthesis and in industrial products such as varnishes. It is colorless and miscible in water, with a boiling point of 66 ºC. It is highly flammable but relatively nontoxic. When stored in air, it can form explosive peroxides, but this can be prevented by adding an inhibitor such as butylated hydroxytoluene (BHT).
