Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of benzimidazole-based pharmaceuticals. It serves in the development of antiparasitic and antiviral agents due to its ability to form stable ring structures with biological activity. Also employed in research for designing enzyme inhibitors and in the production of dyes and fluorescent markers owing to its amine functionality and aromatic structure. Its diaminoguanidine-like structure makes it valuable in coordination chemistry and catalyst design.
