Applications

Synthesis and Liquid ChromotographyTetrahydrofuran is used as a solvent in Grignard reagent formation processes, pharmaceutical steroids and in the preparation of organometallic reagents. It is used for HPLC, spectrophotometry and environmental testing. It is used as a resin solvent in flexographic inks for plastics coating deposition for audio and video tapes. It is used in PVC and CPVC pipe cements, polyurethane coatings and in PVC film castings.

Notes

Water <100ppm evaporation residue <5ppmHighly flammable. Oxidizes readily in air to form unstable peroxides. THF exhibits high volatility and an extremely low freezing point. Keep the container tightly closed and sealed until ready for use.
