1,3-Difluorobenzene Chemical Properties,Usage,Production
Synthesis
Higher yields were observed when CsF and HF were reacted with 1,3-dichlorobenzene,
which gave I ,3-difluorobenzene.
Chemical Properties
1,3-Difluorobenzene (C6H4F2, CAS registry No. 372-18-9) is also named as m-difluorobenzene, which is a clear colorless to yellowish liquid. Its melting point is -59 °C, boiling point is 83 °C and flash point is 2 oC. It is insoluble in water and stable under normal temperatures and pressures. It is toxic and flammable. It will produce toxic fluoride gas by heat.
Uses
1,3-Difluorobenzene has been extensively used in the synthesis of pharmaceutical and pesticide intermediate. For example, it can be used for the synthesis of fluorinated medicine such as Fluconazole, etc. and pesticide (Flucycloxuron, Diflubenzuro, etc.). It can also be used to synthesize liquid crystal materials.
Chemical Properties
CLEAR COLORLESS TO YELLOWISH LIQUID
Uses
It is used in the laser induced fluorencence matrix study of 1,3-difluorobenzene radical cation. It is also used synthesis of 1,2,3-triazole containing fluconazole analogues.
Definition
ChEBI: A difluorobenzene carrying fluoro groups at positions 1 and 3.
