Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its aldehyde and amide functional groups allow for versatile chemical transformations, such as condensation reactions to form Schiff bases or heterocyclic compounds. Commonly employed in the development of active pharmaceutical ingredients (APIs) where aromatic aldehydes are needed for coupling reactions. Also utilized in dye synthesis and in the production of specialty polymers due to its bifunctional reactivity.
