Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with pyrazole moieties. Its aldehyde and bromo functional groups allow for versatile coupling reactions, making it valuable in constructing complex heterocyclic compounds. Commonly employed in medicinal chemistry for creating kinase inhibitors and anti-inflammatory agents. Also utilized in the preparation of fluorescent probes and organic semiconductors due to its conjugated structure.
