What is the meaning of Furon?

noun. a colourless flammable toxic liquid heterocyclic compound, used in the manufacture of cotton textiles and in the synthesis of nylon. Formula: C 4 H 4 OAlso called: furfuran.

Why is furan toxic?

It has been classified as a nongenotoxic carcinogen. Furan is thought to be activated to a reactive intermediate, cis-2-butene-1,4-dial that alkylates proteins leading to a toxic response. The resulting chronic toxicity stimulates cell replication, which increases the likelihood of tumor production.
