Used as a building block in organic synthesis, particularly in the preparation of fluorinated pharmaceuticals and agrochemicals due to its electron-deficient aromatic ring which enhances reactivity in cross-coupling reactions. Its perfluorinated structure improves metabolic stability and lipophilicity in drug design. Also employed in materials science for synthesizing liquid crystals and functional polymers with unique electronic properties. Additionally, it serves as a derivatizing agent for detecting and analyzing alcohols and amines in analytical chemistry.
