Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its aldehyde and ester functional groups allow for selective reactions, making it valuable in constructing complex molecules. Commonly employed in the development of active pharmaceutical ingredients (APIs), especially in the formation of heterocyclic compounds. Also utilized in research settings for derivatization and cross-coupling reactions due to the presence of the bromine atom, which facilitates metal-catalyzed transformations like Suzuki or Heck reactions.
