Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of heterocyclic compounds. Its bromine functionality allows for further derivatization through cross-coupling reactions, making it valuable in medicinal chemistry for building complex molecules. Also employed in the preparation of fluorescent dyes and organic electronic materials due to its aromatic structure and reactivity. Commonly utilized in research settings for constructing ligands and metal-organic frameworks (MOFs) where ester groups can coordinate with metal ions.
