1,2-Bis(trifluoromethyl)benzene(CAS: 433-95-4)

1,2-Bis(trifluoromethyl)benzene (CAS: 433-95-4) is a colorless, crystalline solid with a high melting point of 86.5°C. The molecular weight is 217.09 g/mol. It has limited water solubility and is highly soluble in organic solvents such as benzene, toluene, and chloroform. This compound is chemically stable under normal conditions but reacts with strong reducing agents. It is used in the synthesis of various pharmaceuticals and materials due to its unique trifluoromethyl substituents.

1,2-Bis(trifluoromethyl)benzene is synthesized via the Friedel-Crafts alkylation of benzene with trifluoromethyl chloride in the presence of aluminum chloride as a catalyst. This method provides good yield and selectivity. Alternatively, it can be produced using bromobenzene and trifluoromethyl sulfonic acid in acetic acid, which is a more contemporary approach.

1,2-Bis(trifluoromethyl)benzene (CAS: 433-95-4) is primarily used in the pharmaceutical industry for the synthesis of drug intermediates and in the polymer industry for the production of high-performance materials. It also finds applications in the development of sensors, semiconductors, and electronic devices due to its unique properties.

When handling 1,2-Bis(trifluoromethyl)benzene (CAS: 433-95-4), appropriate personal protective equipment (PPE) should be worn, including gloves, goggles, and a lab coat. It should be stored in a fume hood or a well-ventilated area. Spills should be handled with caution using appropriate chemicals and equipment. Always refer to the safety data sheet (SDS) for detailed handling and disposal instructions.
