Used as a key intermediate in the synthesis of organic semiconductors, particularly in the development of conjugated polymers for electronic devices such as organic field-effect transistors (OFETs) and organic photovoltaics (OPVs). Its structure supports effective π-conjugation and facilitates bromine-based coupling reactions, like Suzuki or Stille couplings, enabling the construction of complex heterocyclic systems. Also employed in the preparation of functionalized thiophene-based materials with tailored optoelectronic properties.
