Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its structure allows for selective functionalization, making it valuable in the development of active pharmaceutical ingredients (APIs) and in the construction of complex naphthalene-based molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to form carbon-carbon bonds, enabling the synthesis of substituted naphthalenes with tailored properties. Also finds use in the production of dyes, fluorescent agents, and specialty polymers due to the aromatic and electron-rich nature of the naphthalene core.
