C6H4FNO2

C6H4FNO2 is the molecular formula for several isomers, with nitrophenols and fluoronitrobenzenes being common examples. One notable isomer is 4-fluoronitrobenzene, a colorless to pale yellow crystalline solid. It has a melting point of around 27-29 degrees Celsius and a boiling point of approximately 215-216 degrees Celsius. 4-Fluoronitrobenzene is sparingly soluble in water but soluble in organic solvents like ethanol and ether. It is a chemical intermediate used in the synthesis of various organic compounds, including dyes, pharmaceuticals, and agricultural chemicals. Its reactivity stems from the presence of both the electron-withdrawing nitro group and the electronegative fluorine atom on the benzene ring, which can undergo nucleophilic aromatic substitution reactions. Another possible isomer is 2-fluoronitrobenzene, which is also a solid with similar solubility characteristics but a different melting and boiling point. The specific properties and applications depend on the precise arrangement of the fluorine and nitro substituents on the phenyl ring. Safety precautions are necessary when handling these compounds due to their potential toxicity and irritant properties.
