Used as a versatile reagent in organic synthesis, particularly in cross-coupling reactions to form carbon-carbon and carbon-heteroatom bonds. It serves as a key intermediate in the preparation of pharmaceuticals, agrochemicals, and fine chemicals. Its triflate group is highly reactive, making it valuable in palladium-catalyzed reactions like Suzuki, Heck, and Sonogashira couplings. It is also employed in the synthesis of complex molecules, including natural products and active pharmaceutical ingredients, due to its ability to introduce pyridine moieties efficiently.
