Tetrahydrofuran (THF), inhibitor-free, ≥99.9% purity, is a high-performance solvent suitable for HPLC and analytical laboratory applications. This HPLC-grade solvent offers controlled impurity levels, low non-volatile residue, and defined UV absorbance characteristics for reliable chromatographic performance.

Free from stabilizing inhibitors, this grade is appropriate for applications requiring pure solvent systems, including polymer research, spectrophotometry, environmental testing, and IR spectroscopy. THF is widely used as a solvent in organic synthesis, polymer dissolution, and materials research due to its strong solvating capability and miscibility with water and many organic solvents.
