CAS No. 17928-28-8 is an organic compound known as tetrahydrofuran (THF). It is a colorless, flammable liquid with a sweet smell. THF is a cyclic ether, which means it contains an oxygen atom bonded to two hydrogen atoms, forming a ring-like structure. It is an important solvent in the chemical industry and is used in many different applications.

THF is used in the production of polymers, including polyester and polyurethane, as well as in the production of pharmaceuticals. It can be used as a solvent for fats, oils, and waxes, and in the manufacture of dyes and cosmetics. It is also used in the production of polyvinyl chloride (PVC).

THF is a highly polar solvent, meaning that it is able to dissolve many polar compounds, such as alcohols, acids, and bases. It has a low boiling point and a high solubility in water. It is also relatively non-toxic and non-flammable, making it a safe choice for many industrial applications.

THF is produced by the catalytic hydrogenation of furan. It is also produced as a byproduct of the production of ethylene oxide, which is used in the manufacture of polyethylene. THF is used in a wide variety of industries, including the production of polymers, pharmaceuticals, dyes, and cosmetics.

The toxicity of THF is relatively low. It is classified as a slightly flammable liquid and is not considered hazardous to human health. However, it should be handled with care, as it can cause skin, eye, and respiratory irritation. It is also combustible and should not be stored near open flames or other sources of ignition.
