Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its aldehyde functional group allows for easy modification, making it valuable in constructing more complex heterocyclic compounds. Commonly employed in medicinal chemistry for drug discovery programs targeting cancer, inflammation, and neurological disorders. Also utilized in the preparation of fluorescent probes and agrochemicals due to its stable aromatic framework and reactivity profile.
