Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic receptor ligands and other biologically active compounds. It serves as a building block in medicinal chemistry for creating heterocyclic structures with potential neurological or anti-inflammatory effects. Also employed in agrochemical research for designing novel pesticides and herbicides due to its ability to modify molecular reactivity in complex organic frameworks. Its aldehyde functional group allows for easy derivatization, making it valuable in combinatorial chemistry and high-throughput screening.
