Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block in the formation of more complex naphthalene derivatives through cross-coupling reactions such as Suzuki or Heck reactions. Commonly employed in research settings to introduce the methylnaphthyl group into target molecules. Also utilized in the development of functional materials, including organic semiconductors and fluorescent dyes, due to the aromatic stability and electronic properties of the naphthalene core.
