Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for further functionalization through cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex thiophene-based molecules. The presence of the α,β-unsaturated ester moiety makes it suitable for Michael addition reactions, useful in forming carbon-carbon bonds. It is also employed in the development of conjugated systems for materials science applications, including organic semiconductors and electronic materials.
