Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its heterocyclic scaffold, which exhibits strong binding affinity to biological targets. Also employed in agrochemical research for designing novel pesticides with improved efficacy and selectivity. Its aldehyde functional group allows for easy modification, enabling the creation of diverse compound libraries for drug discovery and structure-activity relationship studies.
