Used as a key intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of fused ring systems like pyrazines and imidazoles. Its high nitrogen content and reactive amino groups make it valuable in developing pharmaceuticals, agrochemicals, and functional materials. It is also employed in the production of dyes and pigments due to its ability to form conjugated systems. Additionally, it serves in coordination chemistry as a ligand precursor for metal-organic frameworks and catalysts.
