Tetrahydrofuran CAS 109-99-9

Tetrahydrofuran is a polar aprotic cyclic ether solvent, commonly referred to as THF and oxolane, used extensively as a reaction medium in polymer synthesis solvent applications. It dissolves a wide range of polymers and reactive intermediates and supports controlled reaction environments in processes such as polymerization and chemical transformation, due to its low viscosity and favorable solvating behavior (CAS 109-99-9). In industrial chemical supply contexts, tetrahydrofuran is provided with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and options for bulk supply.

FAQ - Technical & Supply Chain

  • Q:

    Do tetrahydrofuran and oxolane refer to the same chemical substance?

    A: Yes. Tetrahydrofuran and oxolane are different names for the same compound and correspond to a single CAS identity.
  • Q:

    Is tetrahydrofuran primarily used as an industrial solvent rather than only for laboratory research?

    A: Tetrahydrofuran is commonly used as an industrial solvent in polymer synthesis and chemical processing, where it serves as a reaction medium or dissolving agent in manufacturing-scale operations.
