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 the preparation of active pharmaceutical ingredients (APIs) due to its ability to form imine or amine derivatives that are pharmacologically active. Its structure allows for easy modification in drug design, making it valuable in medicinal chemistry for creating compounds with improved binding affinity and selectivity. Also employed in the production of agrochemicals and specialty organic materials where aromatic aldehydes with constrained amines are required.
