Application

1,2-Difluoro-4-nitrobenzene is widely used as a versatile building block in organic synthesis, particularly in the preparation of fluorinated pharmaceuticals and agrochemicals. Its electron-deficient aromatic ring makes it a valuable substrate for SNAr reactions to introduce heteroatoms or functional groups. Researchers also utilize it in the development of liquid crystals, OLED materials, and specialty polymers. The compound’s nitro group can be reduced to an amine for further derivatization.
