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 reactions, enabling the construction of complex aromatic systems. Commonly employed in medicinal chemistry for modifying lead compounds to improve potency and selectivity. Also utilized in materials science for creating specialty organic semiconductors and liquid crystals due to its rigid structure and electron-withdrawing trifluoromethoxy group.
