U.S. EPA. IRIS Toxicological Review of Tetrahydrofuran (THF) (Interagency Science Discussion Draft). U.S. Environmental Protection Agency, Washington, DC, EPA/635/R-11/006D, 2011.
The draft Toxicological Review of Tetrahydrofuran provides scientific support and rationale for the hazard identification and dose-response assessment pertaining to chronic exposure to tetrahydrofuran. Tetrahydrofuran, or THF, is used as a solvent for polyvinyl chlorides, vinylidene chloride polymers, natural and synthetic resins (particularly vinyls), in topcoating solutions, polymer coatings, cellophane, protective coatings, adhesives, magnetic strips and printing inks. It is also used for Grignard and metal hydride reactions. THF is used as an intermediate in chemical synthesis. For example, it is used in the preparation of chemicals including adipic acid, butadiene, acrylic acid, butylrolactone, succinic acid, 1,4-butanediol diacetate, motor fuels, vitamins, hormones, pharmaceuticals, synthetic perfumes, organometallic compounds, and insecticides. It is also used in the manufacture of polytetramethylene ether glycol, polyurethane elastomers, and elastic polymers. THF can be used in the fabrication of materials for food packaging, transport, and storage.
