Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in reactions involving palladium-catalyzed coupling due to the presence of the ethynyl group. The bromine atom enables cross-coupling reactions such as Suzuki or Heck couplings, allowing for the construction of complex aromatic systems. The trifluoromethoxy group contributes enhanced lipophilicity and metabolic stability, making this compound valuable in the development of bioactive molecules, including potential candidates in medicinal chemistry for central nervous system agents or anti-inflammatory drugs. It is also employed in materials science for designing organic semiconductors and functional polymers.
