Tetrahydrofuran (THF), or oxolane, is an organic compound with the formula (CH 2) 4 O. The compound is classified as heterocyclic compound, specifically a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity. It is mainly used as a precursor to polymers.
The highest THF value in the blood was at 1 hr post-application (about 200 mg/kg). The biological half-life in blood was 5 hr. 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.
