Toxicity: Isolated from coal oil and used in the manufacture of coumarone-indene resin. This resin is used in paints, glue, etc. and is allowed in food packaging. Little is known about the toxicity of benzofuran to humans but acute toxicity in experimental animals involves liver and kidney failure. Chronic toxicity to animals involves damage to the liver, kidneys, lungs, and stomach. Lifetime administration (oral administration) caused cancer in both rats and mice.

Use

2,3-Benzofuran is a colorless, sweet-smelling, oily liquid made by processing coal into coal oil. It may also be formed during other uses of coal or oil. 2,3-Benzofuran is not used for any commercial purposes, but the part of the coal oil that contains 2,3-benzofuran is made into a plastic called coumarone-indene resin. This resin resists corrosion and is used to make paints and varnishes. The resin also provides water resistance and is used in coatings on paper products and fabrics. It is used as an adhesive in food containers and some asphalt fl oor tiles. The resin has been approved for use in food packages and as a coating on citrus fruits. We do not know how often the resin is used or whether any 2,3-benzofuran in the coating or packaging gets into the food. 2,3-Benzofuran may enter the air, water, and soil during its manufacture, use, or storage at hazardous waste sites. Breathing contaminated air or touching the chemical in the workplace is the source of human exposure.
