Used as a key intermediate in organic synthesis, particularly in the preparation of conjugated polyenes and stilbene derivatives. Its brominated structure allows for further cross-coupling reactions, such as Suzuki or Heck couplings, enabling the construction of complex aromatic and olefinic systems. Commonly employed in the development of organic electronic materials, including semiconductors and fluorescent dyes, due to its extended π-conjugation. Also utilized in photochemical studies where controlled double bond geometry influences reactivity and energy transfer.
