2,4-Difluoro-1-(trifluoromethyl)benzene(CAS: 64248-61-9)

2,4-Difluoro-1-(trifluoromethyl)benzene has a crystalline form and a molecular weight of approximately 242.05 g/mol. It is slightly soluble in water but soluble in common organic solvents. The compound exhibits moderate electronic reactivity and can participate in electrophilic aromatic substitution reactions. It also shows good thermal stability up to 200°C.

2,4-Difluoro-1-(trifluoromethyl)benzene is typically synthesized through the Friedel-Crafts alkylation of 2,4-difluorotoluene using trifluoromethylating agents like trifluoromethyl sulfonic acid. This process involves the use of Lewis acids as catalysts and requires precise temperature control to achieve good selectivity and yield.

2,4-Difluoro-1-(trifluoromethyl)benzene finds applications in the pharmaceutical industry for the synthesis of certain drugs, in polymer chemistry for the development of specialized resins, and in semiconductor manufacturing for etching processes. It is also used in the production of sensors due to its unique electronic properties.

When handling 2,4-Difluoro-1-(trifluoromethyl)benzene, care should be taken to use personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be handled in a well-ventilated area or a fume hood to minimize inhalation risks. Spills should be cleaned up carefully, and the material safety data sheet (MSDS) should be consulted for specific disposal instructions. This compound is not flammable, but care must be taken due to its reactivity and potential for skin and eye irritation.
