Nonetheless, guidelines have been created to make it easier. However, as with many properties, the polarity is a continuous scale, and the correct question is not "is it polar or non-polar" but "how polar is it." Vestn.Khar'k.Univ. : Physico-chemical properties of binary solvent ethylene glycol-tetrahydrofuran. Solvents are generally classified by the polarity, and considered either polar or non-polar, as indicated by the dielectric constant. : Dielectric Constant Against Temperature for 43 Liquids. ; Deshpande C.M. The data represent a small sub list of all available data in the Dortmund Data Bank. 37 (1960) 1-10, Schornack L.G. : Dielectric Constant and Dipole Moment: Ethers, Aldehydes and Chloro COmpounds. : Nuclear Magnetic Resonance Relaxation, Permittivity, Viscosity and Ultrasonic Velocity Measurements in Binary Mixtures of Methanol and Tetrahydrofuran. ; Singh J.; Ludwig R.; Zeidler M.D. : Untersuchung der Wechselwirkung im System N-Methylformamid - Tetrahydrofuran. ; Surov Yu.N. THF concentrations in adipose tissue and kidneys were 1.3-1.4 times higher than in blood; levels in liver, brain, spleen, and muscle were similar to blood.
