Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active molecules. Its aldehyde and bromo functional groups allow for further chemical modifications, such as cross-coupling reactions and nucleophilic substitutions, making it valuable in constructing complex organic frameworks. Commonly employed in medicinal chemistry for building blocks in drug discovery programs. Also utilized in the preparation of fluorescent probes and specialty materials due to its aromatic and reactive nature.
