Used as an intermediate in organic synthesis, particularly in palladium-catalyzed cross-coupling reactions to form carbon-carbon bonds. It serves as an electrophilic naphthalene derivative, enabling the introduction of naphthyl groups into complex molecules. Commonly applied in the development of pharmaceuticals, agrochemicals, and functional materials due to its reactivity in transformations such as Suzuki and Heck couplings. Its triflate group enhances leaving group ability, making it highly effective in catalytic reactions. Also utilized in the preparation of fluorescent dyes and optoelectronic materials owing to the aromatic naphthalene backbone.
