2,6-Dichloro-4-(trifluoromethyl)benzonitrile(CAS: 157021-61-9)

2,6-Dichloro-4-(trifluoromethyl)benzonitrile is a colorless to white crystalline solid. It has a molecular weight of approximately 263.04 g/mol. This compound is not very soluble in water but is soluble in common organic solvents such as ethanol and acetone. It shows moderate reactivity, particularly in nucleophilic substitution reactions, and is less reactive towards electrophiles compared to its unsubstituted analogues.

2,6-Dichloro-4-(trifluoromethyl)benzonitrile is typically synthesized via the reaction of 2,6-dichlorotoluene with trifluoroacetonitrile in the presence of a suitable base such as potassium carbonate. The reaction is carried out under anhydrous conditions, and the yield is generally good, around 70-80%. This synthesis involves the nucleophilic substitution of the toluene ring with trifluoromethyl and nitrile groups.

2,6-Dichloro-4-(trifluoromethyl)benzonitrile is used in the pharmaceutical industry for the synthesis of certain intermediates, in the polymer industry as a monomer for specialty polymers, and in the chemical sensor industry for gas detection. It also finds application in the semiconductor industry as a precursor for the fabrication of electronic materials.

When handling 2,6-Dichloro-4-(trifluoromethyl)benzonitrile, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be carried out in a well-ventilated area or a fume hood. In case of a spill, it should be immediately cleaned up using appropriate methods. Always refer to the Safety Data Sheet (SDS) for detailed information on handling and storage procedures.
