Used as an intermediate in organic synthesis, particularly in the preparation of naphthalene-based pharmaceuticals and agrochemicals. Its reactive bromomethyl and chloro groups allow for selective substitutions, making it valuable in constructing complex molecules. Commonly employed in the development of fluorescent dyes and optoelectronic materials due to the naphthalene core’s photophysical properties. Also utilized in cross-coupling reactions to form carbon-carbon bonds in research settings.
