4-Fluorobenzonitrile is widely used in the synthesis of pharmaceuticals and agrochemicals due to its versatile reactivity. It serves as a key intermediate in the production of various active ingredients, particularly in the development of antifungal, antibacterial, and anti-inflammatory drugs. Its fluorine atom enhances the biological activity and metabolic stability of the compounds derived from it. Additionally, it is employed in the manufacture of liquid crystals, which are essential components in display technologies like LCDs. The compound’s nitrile group also makes it valuable in organic synthesis, where it can be converted into other functional groups such as carboxylic acids or amines. Its applications extend to the field of materials science, where it is used in the preparation of polymers and specialty chemicals.
