Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules. Its reactive aldehyde and bromine groups allow for versatile functionalization, making it valuable in constructing heterocyclic compounds. Commonly employed in cross-coupling reactions to form C–C bonds, it plays a role in creating kinase inhibitors and antifungal agents. Also utilized in medicinal chemistry for building blocks in drug discovery programs targeting central nervous system disorders and inflammatory diseases.
