Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals due to its ability to introduce fluorinated aromatic groups, which can enhance metabolic stability and bioavailability. It serves as a building block in the preparation of sulfonate esters and sulfonamides, commonly found in active pharmaceutical ingredients. Also employed in the development of dyes and functional materials where electron-withdrawing substituents are required. Its fluorine atom allows for specific interactions in drug-receptor binding, making it valuable in medicinal chemistry research.
