Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its structure supports the development of complex molecules, particularly in the preparation of substituted naphthalene derivatives. Commonly employed in coupling reactions to form carbon-carbon bonds, especially in palladium-catalyzed processes like Suzuki or Heck reactions. Also utilized in the synthesis of dyes, fluorescent agents, and functional materials due to the aromatic stability and electron-rich nature of the naphthalene core. The chloro group serves as a good leaving group, enabling nucleophilic substitution, while the methoxy group directs electrophilic substitution and enhances solubility in organic solvents.
