Tetrahydrofuran ist eine farblose, brennbare Flüssigkeit mit etherartigem Geruch. Es ist mit Wasser bis zu einer Temperatur von 71,8 °C vollständig mischbar, oberhalb dieser Temperatur bildet sich eine kleine Mischungslücke aus, die sich bei 137,1 °C wieder schließt. Die Mischung mit Wasser erfolgt unter Volumenkontraktion. Mit Alkoholen, Ketonen und Ethern ist THF unbegrenzt mischbar.

Tetrahydrofuran (THF) is a contaminant of exposure and appears in human biofluids. The Food and Drug Administration (FDA) has announced recommendations to revise the permitted daily exposures for THF, and so has the International Conference on Harmonisation. THF oxidizes readily, which can lead to instability and result in cytotoxicity.

Tetraidrofurano, abreviado comumente como THF (do inglês tetrahydrofuran), é um composto orgânico heterocíclico, especificamente um éter cíclico, usado como solvente, obtido pela hidrogenação do furano, com fórmula (CH 2) 4 O. . Apresenta-se como um líquido incolor, de baixa viscosidade, constante dielétrica de 7,6, odor semelhante ao de éter etílico. É solúvel em água.
Tetrahydrofuran. Basis for original (SCP) IDLH: AIHA  reported that exposure to 25,000 ppm will cause anesthesia and that 17,000 ppm appears to be safe for 3 hours [Hofmann and Oettel 1954]. Therefore, 20,000 ppm has been chosen as the IDLH because it is the lower explosive limit (LEL) of tetrahydrofuran. Short-term exposure guidelines: None developed.
