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.
Application
Meets Reagent Specifications for testing USP/NF monographs OmniSolv®
TX0279P-1 is packaged in poly coated glass bottles
Tetrahydrofuran is used as solvent
- To prepare mobile phase in reversed-phase liquid chromatography
- In the preparation of Spin-Coated Polymer Thin Films
- In the synthesis of diacetylinic aryloxysilane polymers by polycondensation reaction
- In the formation of grignard reagent which is used for organic sythesis
