14difluorobenzene

1,4-Difluorobenzene is an organic compound with the chemical formula C6H4F2. It is a colorless liquid at room temperature and pressure, with a distinct aroma. It is a disubstituted benzene ring where two fluorine atoms are positioned opposite each other, in a para orientation. This symmetrical structure influences its physical and chemical properties.

1,4-Difluorobenzene is soluble in many organic solvents but has limited solubility in water. Its boiling point is around 88-89 degrees Celsius, and its melting point is approximately -14 degrees Celsius. The presence of the electronegative fluorine atoms affects the electron distribution within the benzene ring, making it less susceptible to electrophilic aromatic substitution compared to benzene itself. However, it can undergo nucleophilic aromatic substitution under specific conditions.

This compound finds applications as a building block in organic synthesis, particularly in the pharmaceutical and agrochemical industries. It is used as a precursor for the synthesis of more complex fluorinated organic molecules, which often exhibit unique biological activities or material properties. For instance, it can be incorporated into liquid crystal displays and polymers due to the influence of fluorine on their optical and physical characteristics. Its production typically involves fluorination reactions of benzene derivatives.
