Used as a key intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki-Miyaura and Heck reactions, due to the presence of the trifluoromethylsulfonyloxy (triflate) leaving group. This compound enables the formation of carbon-carbon bonds in the preparation of complex naphthalene derivatives, which are often found in pharmaceuticals, agrochemicals, and functional materials. Its high reactivity as an electrophile makes it valuable in catalytic reactions where efficient substitution is required. Also employed in the synthesis of polycyclic aromatic systems and conjugated materials for optoelectronic applications.
