Description

General description

Tetrahydrofuran (THF), is a colorless, volatile, heterocyclic saturated cyclic ether characterized by low viscosity and high solubility in various solvents. It is widely used as a polar aprotic, water-miscible organic solvent in various organic synthesis, particularly for reactions involving organometallic compounds and Grignard reagents. Additionally, THF plays an important role as a solvent in the synthesis of many API’s and in polymerization processes.
