Used as a key reagent in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions. It serves as an effective electrophile for introducing the 2-chlorophenyl group in the construction of biaryl and heterobiaryl compounds, which are common scaffolds in pharmaceuticals and agrochemicals. Its triflate leaving group enables high reactivity under mild reaction conditions, making it valuable in the synthesis of complex molecules, including drug intermediates and functional materials. Also employed in the preparation of ligands for catalysis and in the development of fluorescent dyes and electronic materials due to its stability and reactivity profile.
