Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for vinyl halide reactivity, making it suitable for coupling reactions such as Heck or Suzuki reactions to build more complex aromatic systems. The methoxy group enhances electron density on the aromatic ring, influencing regioselectivity in electrophilic substitutions. Also explored in the development of liquid crystals and organic semiconductors due to its conjugated framework and ability to undergo functionalization.
