Cas No: 74-96-4
CAS NO. 74-96-4 is a unique numerical identifier assigned by the Chemical Abstracts Service (CAS) to a chemical substance. It is also referred to as the CAS Registry Number and is used to identify a substance when searching through databases. This number is assigned to Tetrahydrofuran (THF), an organic compound with the chemical formula C4H8O.
Tetrahydrofuran is a colorless, low-viscosity liquid with a mild ether-like odor. It is soluble in water, ethanol, chloroform, and other polar and non-polar solvents. The compound is miscible with many organic solvents and is used as a solvent and reagent in many industrial applications.
Tetrahydrofuran is used in the production of polytetramethylene ether glycol (PTMEG), a polyether glycol used in the manufacture of polyurethanes, elastomers, and coatings. It is also used as a solvent for paints and coatings, as a reaction medium for the production of pharmaceuticals, and as a fuel additive. It is also used in the synthesis of other organic compounds, such as ethers, amines, and aldehydes.
Tetrahydrofuran is a flammable liquid and can be a skin and eye irritant. It may also have adverse effects on the nervous system. Therefore, protective clothing and equipment should be worn when handling this compound. It is important to store tetrahydrofuran in a cool, dry area and away from any sources of ignition.
Tetrahydrofuran is an important industrial chemical and its CAS NO. 74-96-4 is used to identify the material. The compound has a wide range of uses in industries ranging from pharmaceuticals to coatings and fuel additives. It is important to take proper safety precautions when handling this compound to avoid any adverse health effects.
