Used in organic synthesis as a building block for pharmaceuticals and agrochemicals due to its fluorinated aromatic structure. The presence of fluorine atoms enhances metabolic stability and bioavailability in drug design, making it valuable in developing bioactive molecules. Also employed in the preparation of cinnamic acid derivatives for research in photopolymerization and UV-absorbing materials. Its trans configuration supports conjugation and planarity, beneficial in studies of nonlinear optical materials.
