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, oximes, or extended conjugated systems useful in drug design. Commonly employed in agrochemical research for creating novel pesticides and herbicides due to its stable heterocyclic core. Also utilized in the preparation of fluorescent probes and dyes, where the methoxy and methyl substituents enhance electron-donating properties and influence photophysical behavior.
