Frequently asked questions
What is unstabilised tetrahydrofuran (THF) commonly used for?
Unstabilised THF is primarily used as a high-purity solvent in chemical synthesis, polymerisation reactions, and as a reagent in laboratory-scale organic chemistry due to its low water content and absence of inhibitors.
What is the molecular formula and molecular weight of tetrahydrofuran?
The molecular formula of tetrahydrofuran is **C₄H₈O**, and its molecular weight is **72.11 g/mol**.
How should unstabilised tetrahydrofuran be stored?
Store unstabilised THF in a tightly sealed container at **ambient temperature**, away from ignition sources, as it is highly flammable and can form peroxides over time.
