Product Description
Tetrahydrofuran,
THF, is a heterocyclic organic compound. It belongs to the ether
class and is the complete hydrogenation product of the aromatic
compound furan. Tetrahydrofuran is one of the strongest polar
ethers, used as a medium polar solvent in chemical reaction and
extraction, colorless volatile liquid at room temperature, known
as "universal solvent".
At room
temperature, it is partially miscible with water, and some
illegal reagent vendors use this to make huge profits on
tetrahydrofuran reagents mixed with water. Due to the tendency of
THF to form peroxide in storage, industrial products are
generally added with the antioxidant BHT. Moisture content <
=0.2%. It has the characteristics of low toxicity, low boiling
point and good fluidity.
