Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for cardiovascular and central nervous system drugs. Its functional groups allow for selective modifications, making it valuable in constructing complex organic molecules. Commonly employed in cross-coupling reactions and as a building block in agrochemicals and specialty chemicals. Its aldehyde group facilitates condensation reactions, enabling the formation of Schiff bases and other derivatives for use in medicinal chemistry research.
