Used primarily as an intermediate in organic synthesis, this compound plays a key role in the preparation of pharmaceuticals and fine chemicals. Its aldehyde and bromo functionalities allow for diverse chemical transformations, making it valuable in constructing complex aromatic molecules. It is often employed in carbon-carbon bond-forming reactions, such as Wittig or Grignard reactions, and can serve as a building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those with aryl-substituted structures. Additionally, it may be used in the development of agrochemicals and specialty materials where functionalized aromatic aldehydes are required.
