Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen atom. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature. It is soluble in common organic …

The kinetics of furan biotransformation of male F344 rats were studied in vivo and in vitro in order to understand target tissue dosimetry. A physiologically based pharmacokinetic (PBPK) model for furan in rats was developed from gas uptake studies using the initial furan concn of 100, 500, 1050, and 3850 ppm.

Furan, any of a class of organic compounds of the heterocyclic aromatic series characterized by a ring structure composed of one oxygen atom and four carbon atoms. The simplest member of the furan family is furan itself, a colourless, volatile, and somewhat toxic liquid that boils at 31.36° C

Furan. H. Robles, in Encyclopedia of Toxicology (Third Edition), 2014 Mechanism of Toxicity. Furan can cause eye, skin, and mucus membrane irritation, burning sensation and, in severe cases, corrosion. If inhaled, furan may produce pulmonary edema and bronchiolar necrosis. When absorbed, furan can cause central nervous system (CNS) …
