Corrosionpedia Explains Furan

The Latin name for furan is "furfur," which means bran. Its first derivative was 2-furoic acid, which was developed in 1780 by Carl Wilhelm Scheele. In 1831, another derivative called "furfural" was developed by Johann Wolfgang Döbereiner. In 1870, furan was developed for the first time by Heinrich Limpricht and was called "tetraphenol."

The International Union of Pure and Applied Chemistry (IUPAC) has been calling tetraphenol "furan," and it is globally recognized by this name. During the production of pyrrole, thiophene and tetrahydrofuran, furan is used. When inhaled, it causes irritations in eyes and skin, and can cause depression in the central nervous system of the human body.
