Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for functionalization in the development of complex polycyclic compounds. Commonly employed in coupling reactions to form biaryl systems, which are important in drug discovery. Also utilized in the synthesis of fluorescent dyes and organic semiconductors due to the naphthalene backbone’s electronic properties. The bromine atom facilitates cross-coupling reactions such as Suzuki or Heck reactions, making it valuable in building molecular complexity.
