Used in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals due to its halogenated aromatic structure. The bromine atom allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex molecules. Commonly employed as an intermediate in the preparation of bioactive compounds, including potential drug candidates targeting neurological disorders and inflammation. Also utilized in materials science for creating organic semiconductors and optoelectronic materials owing to the electron-rich thiophene core.
