Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of more complex aromatic compounds. Commonly employed in the development of active pharmaceutical ingredients where a phenylacetic acid derivative is required. Also utilized in the synthesis of fragrances and specialty esters due to its stable ester group and reactive aryl bromide moiety.
