Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block in the formation of complex molecules through cross-coupling reactions, such as Suzuki or Heck reactions, where the bromine atoms act as reactive sites. Also employed in the development of functional materials, including organic semiconductors and liquid crystals, due to its stable aromatic backbone and ability to undergo selective functionalization. Its ethyl substituent provides steric and electronic modulation, making it useful in fine-tuning the properties of final products.
