Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. Its brominated structure makes it suitable for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic and heteroaromatic systems. It is also employed in the development of conjugated materials for organic electronics, including semiconductors and optoelectronic devices, due to the thiophene core’s electron-rich nature. Additionally, it serves as a building block in the synthesis of dyes and functional polymers.
