2,4-Difluorobenzonitrile(CAS: 3939-09-1)

2,4-Difluorobenzonitrile (CAS: 3939-09-1) is a colorless or light yellow liquid with a density of approximately 1.12 g/cm³. It has a molecular weight of 138.08 g/mol and a boiling point around 174-175°C. Soluble in common organic solvents like ethanol and chloroform. It reacts readily with nucleophiles and can act as a cyanide source in chemical syntheses.

2,4-Difluorobenzonitrile (CAS: 3939-09-1) can be synthesized via the reaction of 2,4-difluorobenzoyl chloride with ammonia or an amines. Alternatively, it can be prepared by fluorination of 2,4-dinitrobenzonitrile followed by reduction of the nitro groups. Common catalysts include Lewis acids or transition metals.

2,4-Difluorobenzonitrile (CAS: 3939-09-1) is used in the pharmaceutical industry for the synthesis of active pharmaceutical ingredients, in polymer chemistry as a monomer, and in the development of sensors and semiconductors due to its unique electronic properties.

When handling 2,4-Difluorobenzonitrile (CAS: 3939-09-1), ensure the use of personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Conduct reactions under fume hood to minimize exposure. Spills should be neutralized with an appropriate base and cleaned up using absorbent materials. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal instructions.
