Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of histamine H3 receptor antagonists. Its structure allows for the construction of biologically active molecules targeting neurological disorders such as Alzheimer's disease, epilepsy, and sleep disorders. Also employed in the preparation of imidazole-based functional materials and ligands for metal-organic frameworks due to its nitrogen-rich heterocyclic moiety. Its aldehyde group enables easy functionalization for conjugation in medicinal chemistry and material science applications.
