Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other biologically active compounds. Its aldehyde functional group allows for easy modification, enabling the formation of imines, alcohols, or carboxylic acids, which are valuable in drug design. Commonly employed in medicinal chemistry for constructing heterocyclic systems found in anticancer, anti-inflammatory, and neuroprotective agents. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its aromatic and electron-rich structure.
