About Tetrahydrofuran, GR 99%+

Tetrahydrofuran (CAS 109-99-9) is an analytical reagent grade solvent offered by Vaqora Chemicals (AR grade) with a typical assay of ≥99%. Its molecular formula is C4H8O and its molecular weight is 72.11 g/mol. The IUPAC name is oxolane. Alternative names: THF and Furanidine.

The material typically appears as a colourless clear liquid. Key physical data: a melting point of -108 °C and a density of 0.889 g/mL at 25 °C. Keep containers tightly closed in a cool, well-ventilated area away from heat and ignition sources. Under GHS it is labelled “Danger”, so handle it with suitable PPE and consult the SDS.

It is commonly used for analytical reagent work, extraction and recrystallisation, titrimetric analysis and solvent and extraction work. Buyers come mainly from academic and industrial research and pharmaceutical manufacturing.

Vaqora Chemicals supplies Tetrahydrofuran in 500 mL, 5 L and 180 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
