Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of fluorinated drugs where the fluorine atom enhances metabolic stability and bioavailability. It serves in the preparation of active pharmaceutical ingredients (APIs) for treatments involving central nervous system disorders and anti-inflammatory agents. Also employed in organic synthesis to introduce the 4-fluorobenzoyl moiety, useful in agrochemicals and specialty polymers. Its solubility in water and polar solvents makes it suitable for reactions in aqueous or mixed solvent systems.
