Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It serves as a building block in organic reactions where selective bromo and chloro substitution on a naphthalene ring enables further functionalization through cross-coupling reactions, such as Suzuki or Ullmann reactions. Commonly employed in the development of specialty chemicals, including dyes, fluorescent compounds, and liquid crystals. Its halogenated structure makes it valuable in materials science for modifying electronic properties in organic semiconductors. Also utilized in research settings for preparing labeled compounds and studying reaction mechanisms involving aromatic systems.
