Used as a key intermediate in organic synthesis, particularly in the formation of complex molecules through cross-coupling reactions. It serves as a versatile reagent in the preparation of pharmaceuticals, agrochemicals, and specialty chemicals. Its triflate group acts as a good leaving group, facilitating efficient substitution reactions. Commonly employed in palladium-catalyzed processes, such as Suzuki and Heck reactions, to construct carbon-carbon bonds. Also utilized in the development of liquid crystals and advanced materials due to its ability to introduce functional groups into aromatic systems.
