4-Fluoro-3-(trifluoromethyl)benzonitrile(CAS: 67515-59-7)

4-Fluoro-3-(trifluoromethyl)benzonitrile (CAS: 67515-59-7) is a crystalline solid with a molecular weight of approximately 260.07 g/mol. It has a low solubility in water but is more soluble in organic solvents like ethanol and acetonitrile. The compound is relatively stable but can undergo hydrolysis under basic conditions. It is a strong electrophile and can undergo nucleophilic substitution reactions.

4-Fluoro-3-(trifluoromethyl)benzonitrile can be synthesized via a Friedel-Crafts alkylation of 3-(trifluoromethyl)benzonitrile with fluoroalkyl halides. The reaction typically requires the use of a Lewis acid catalyst, such as aluminum chloride, and is carried out in a suitable organic solvent. The yield is generally good, with selectivity towards the desired product.

4-Fluoro-3-(trifluoromethyl)benzonitrile is used in various industries, including pharmaceuticals for the synthesis of certain drugs, and in the production of polymers and monomers. It also finds applications in sensor technology and as a building block in semiconductor manufacturing processes.

Proper handling of 4-Fluoro-3-(trifluoromethyl)benzonitrile requires the use of personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up carefully using absorbent materials, and the area should be washed down. Always refer to the Safety Data Sheet (SDS) for detailed safety information.
