Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its bifunctional aldehyde groups allow for selective reactions with amines and hydrazines, making it valuable in constructing heterocyclic compounds. Commonly employed in the development of bioactive molecules, including antiviral and anticancer agents. Also utilized in polymer chemistry to introduce piperazine-based cross-linking units, enhancing thermal and chemical resistance of materials.
