1,3-Bis(trifluoromethyl)-benzene Specification

The IUPAC name of this chemical is 1,3-bis(trifluoromethyl)benzene. With the CAS registry number 402-31-3, it is also named as alpha,alpha,alpha,alpha',alpha',alpha'-Hexafluoro-m-xylene. The product's categories are benzene derivatives; aromatic hydrocarbons (substituted) & derivatives. It is clear colourless liquid which is obtained by m-xylene. This chemical is insoluble in water, and soluble in alcohol, ether, benzene. When heated to 90°C a mixture with nitric and sulfuric acids emits spark-sensitive explosive vapors. In addition, the storage environment should be ventilate, low-temperature and dry. Keep 1,3-Bis(trifluoromethyl)benzene separate from oxidants, nitric acid and sulfuric acid. Furthermore, it is used as intermediate of medicine and pesticide. In the camera and watch industry, it is used as a solvent.
