Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of fluorinated compounds with enhanced metabolic stability and bioavailability. Its ethynyl and bromo functional groups allow for versatile coupling reactions, such as Sonogashira and Suzuki couplings, enabling the construction of complex aromatic systems. Commonly employed in medicinal chemistry for creating kinase inhibitors and other biologically active molecules. Also utilized in materials science for designing organic semiconductors and liquid crystals due to its rigid aromatic backbone and electron-withdrawing trifluoromethyl group.
