4-Fluoroaniline
4-Fluoroaniline is an organofluorine compound with the formula. A colorless liquid, it is one of three isomers of fluoroaniline.
4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene.
It is a common building block in medicinal chemistry and related fields. For example, it is a precursor to the fungicide or the fentanyl analogue parafluorofentanyl. It has also been evaluated for the production of ligands for homogeneous catalysis.
